You’re not doing well and finally I don’t have to pretend to be so interested in your on going tragedy, but I’ll rob the bank that gave you the impression that money is more fruitful than words, and I’ll cut holes in the ozone if it means you have one less day of rain. I’ll walk you to the hospital, I’ll wait in a white room that reeks of hand sanitizer and latex for the results from the MRI scan that tries to locate the malady that keeps your mind guessing, and I want to write you a poem every day until my hand breaks and assure you that you’ll find your place, it’s just the world has a funny way of hiding spots fertile enough for bodies like yours to grow roots. and I miss you like a dart hits the iris of a bullseye, or a train ticket screams 4:30 at 4:47, I wanted to tell you that it’s my birthday on Thursday and I would have wanted you to give me the gift of your guts on the floor, one last time, to see if you still had it in you. I hope our ghosts aren’t eating you alive. If I’m to speak for myself, I’ll tell you that the universe is twice as big as we think it is and you’re the only one that made that idea less devastating.

MRI good... X-ray good... blood work good..." If everything's so good, what the hell's she doing here?
Jerry Spinelli (Smiles to Go)
She had not understood what he said, but she took him in with a glance that made Will feel like he had just had one of those full-body MRI scans, the kind that find more things wrong with you than you ever could have imagined.

Human beings don’t deal well with rejection. Back when our ancestors were hunters and gatherers, being ostracized from a tribe was akin to a death sentence. For that reason, rejection is experienced by human beings as being incredibly painful. Studies using functional MRI have shown the same areas of the brain become activated both during rejection and during real physical pain.

When you put a kid who had experienced adversity in an MRI machine, you could see measurable changes to the brain structures.
Nadine Burke Harris (The Deepest Well: Healing the Long-Term Effects of Childhood Trauma and Adversity)
Just like we need food and water, humans need each other. A brain study revealed that when placed in an MRI, a patient's reward center lit up when another person sat in the room. Neurons fire when talk to someone, think about someone, and they go haywire when we hold someone's hand. Our brains and bodies are actually programmed to seek each other out and connect. So then why do so many people prefer being alone? Why do we often run for the hills when we feel the slightest connection? Why we do we feel compelled to fight what we're hardwired to do? Maybe it's because when we find someone or something to hold on to, that feeling becomes like air. And we're terrified we're going to lose it. And trust me, you can get pretty good at the alone thing. But most things are better when they're shared with someone else.
Meredith Grey
When you deeply love someone from that space that is beyond attachment to certain projections or desires, when you love someone just deeply, totally, completely, without any games that the mind or emotions play, then that love remains eternal in the heavens forever, and that is what pulls you back to remembering that love.

The MRI has a repertoire of noises that resemble, in no particular order: a game-show buzzer for a wrong answer, urgent knocking, a modem from 1992, a grizzly-bear growl, and a man with a raspy voice shouting what sounds like "mother cooler!
A.J. Jacobs (Drop Dead Healthy: One Man's Humble Quest for Bodily Perfection)
A few years ago, Tor Wager, a neuroscientist at Columbia University, wanted to figure out why placebos were so effective. His experiment was brutally straightforward: he gave college students electric shocks while they were stuck in an fMRI machine. (The subjects were well compensated, at least by undergraduate standards.)
Jonah Lehrer (How We Decide)
Once you get the hang of it, the practice can create just enough space in your head so that when you get angry or annoyed, you are less likely to take the bait and act on it. There’s even science to back this up—an explosion of new research, complete with colorful MRI scans, demonstrating that meditation can essentially rewire your brain.
Dan Harris (10% Happier)
The activity of loving kindness is the bridge that allows you to slowly, slowly realise the wisdom and perfection of this moment.
Tony Samara
Satisfaction doesn't come from needs and desires or fulfilling them, it comes from being yourself, being true.

A year earlier, I had described campaigns to reporters as “like an MRI for the soul—whoever you are, eventually people find out.
David Axelrod (Believer: My Forty Years in Politics)
In fact, neuroscience research has demonstrated with fMRI studies that when people engage in analytical thought, their ability to empathize is repressed and vice versa.

Michio Kaku (The Future of the Mind: The Scientific Quest to Understand, Enhance, and Empower the Mind)
The conference is geared to people who enjoy meaningful discussions and sometimes "move a conversation to a deeper level, only to find out we are the only ones there." . . . When it's my turn, I talk about how I've never been in a group environment in which I didn't feel obliged to present an unnaturally rah-rah version of myself. . . . Scientists can easily report on the behavior of extroverts, who can often be found laughing, talking, or gesticulating. But "if a person is standing in the corner of a room, you can attribute about fifteen motivations to that person. But you don't really know what's going on inside." . . . So what is the inner behavior of people whose most visible feature is that when you take them to a party they aren't very pleased about it? . . . The highly sensitive tend to be philosophical or spiritual in their orientation, rather than materialistic or hedonistic. They dislike small talk. They often describe themselves as creative or intuitive . . . . They dream vividly, and can often recall their dreams the next day. They love music, nature, art, physical beauty. They feel exceptionally strong emotions--sometimes acute bouts of joy, but also sorrow, melancholy, and fear. Highly sensitive people also process information about their environments--both physical and emotional--unusually deeply. They tend to notice subtleties that others miss--another person's shift in mood, say, or a lightbulb burning a touch too brightly. . . . [Inside fMRI machines], the sensitive people were processing the photos at a more elaborate level than their peers . . . . It may also help explain why they're so bored by small talk. "If you're thinking in more complicated ways," she told me, "then talking about the weather or where you went for the holidays is not quite as interesting as talking about values or morality." The other thing Aron found about sensitive people is that sometimes they're highly empathic. It's as if they have thinner boundaries separating them from other people's emotions and from the tragedies and cruelties of the world. They tend to have unusually strong consciences. They avoid violent movies and TV shows; they're acutely aware of the consequences of a lapse in their own behavior. In social settings they often focus on subjects like personal problems, which others consider "too heavy.
Susan Cain (Quiet: The Power of Introverts in a World That Can't Stop Talking)
In response to an article in the New York times that claimed from an fMRI study that 'a mother's impulse to love and protect her child appears to be hard-wired into her brain' one neuro-curmudgeon put out a plea to 'take experience and learning seriously. Just because you see a response [in the brain] — you don't get to claim it's hard-wired.
Cordelia Fine (Delusions of Gender: How Our Minds, Society, and Neurosexism Create Difference)
The Divine has created this moment in time. It is a very powerful moment, where there is only one way and that way is that you completely let go. Completely let go of what is known, what is safe, and move into the space of beauty.
Tony Samara
Using MRI scans, scientists can now read thoughts circulating in our brains. Scientists can also insert a chip into the brain of a patient who is totally paralyzed and connect it to a computer, so that through thought alone that patient can surf the web, read and write e-mails, play video games, control their wheelchair, operate household appliances, and manipulate mechanical arms. In fact, such patients can do anything a normal person can do via a computer.

For the past ten days, I've had a migraine that follows me like a shadow. One hundred and forty-two hours of incessant pain, an eight on the ten-point scale. My doctor has suggested codeine, which I refused, because once I took too much Percocet after a tooth extraction and threw up for twenty-four hours straight. I have a CT scan, an MRI, I go to the neurologist—the readings are all inconclusive. I'm told it's a migraine with an unknown cause. Have you tried yoga? they say.

(The research on the development of the first MRI scanners was performed by the British company EMI, financed in large part from their profits on Beatles records. “I Want to Hold Your Hand” might well have been titled “I Want to Scan Your Brain.”)
Daniel J. Levitin (This is Your Brain on Music: Understanding a Human Obsession)
You can see the proof in an MRI scan of someone presented with political opinions that conflict with her own. The brain scans of a person shown statements that oppose her political stance show that the highest areas of the cortex, the portions responsible for providing rational thought, get less blood until another statement is presented that confirms her beliefs. Your brain literally begins to shut down when you feel your ideology is threatened. Try it yourself. Watch a pundit you hate for fifteen minutes. Resist the urge to change the channel. Don’t complain to the person next to you. Don’t get online and rant. Try to let it go. You will find this is excruciatingly difficult.
David McRaney (You Are Now Less Dumb: How to Conquer Mob Mentality, How to Buy Happiness, and All the Other Ways to Outsmart Yourself)
Where America really differs from other countries is in the colossal costs of its health care. An angiogram, a survey by The New York Times found, costs an average of $914 in the United States, $35 in Canada. Insulin costs about six times as much in America as it does in Europe. The average hip replacement costs $40,364 in America, almost six times the cost in Spain, while an MRI scan in the United States is, at $1,121, four times more than in the Netherlands. The entire system is notoriously unwieldy and cost-heavy. America has about 800,000 practicing physicians but needs twice that number of people to administer its payments system. The inescapable conclusion is that higher spending in America doesn’t necessarily result in better medicine, just higher costs.

Paul Kalanithi (When Breath Becomes Air)
In an fMRI brain-scan experiment, researchers at Princeton University found that neural resonance disappears when people communicate poorly. The researchers could predict how well people were communicating by observing how much their brains were aligned. And they discovered that people who paid the most attention—good listeners—could actually anticipate what the speaker was about to say before he said it.

Did anyone tell you what the MRI showed?” I asked. “No.” The buck had been passed, as it often was with difficult news. Oftentimes, we’d have a spat with the oncologist over whose job it was to break the news.

different parts of the brain as it thinks. By tracing the path taken by our thoughts, MRI scans have shed new light into the nature of Alzheimer’s, Parkinson’s, schizophrenia, and a host of other mental diseases.
Michio Kaku (The Future of the Mind: The Scientific Quest to Understand, Enhance, and Empower the Mind)
In fact, a recent fMRI study shows that when people use self-talk to reassess upsetting situations, activity in their prefrontal cortex increases in an amount correlated with a decrease of activity in their amygdala.
Susan Cain (Quiet: The Power of Introverts in a World That Can't Stop Talking)
Stanford psychologist Laura Carstensen, to name one such example, used an fMRI scanner to study the brain behavior of subjects presented with both positive and negative imagery. She found that for young people, their amygdala (a center of emotion) fired with activity at both types of imagery. When she instead scanned the elderly, the amygdala fired only for the positive images. Carstensen hypothesizes that the elderly subjects had trained the prefrontal cortex to inhibit the amygdala in the presence of negative stimuli. These elderly subjects were not happier because their life circumstances were better than those of the young subjects; they were instead happier because they had rewired their brains to ignore the negative and savor the positive. By skillfully managing their attention, they improved their world without changing anything concrete about it.
Cal Newport (Deep Work: Rules for Focused Success in a Distracted World)
I once had a client who, terrified of the tight space and restriction involved in getting a head-and-neck MRI, readied himself by lying on the floor with his head under his bed. When that got boring, he upped the ante by lying under the bed with his head duct-taped to the floor. The only problem was that he neglected to warn his wife about his practice and when she found him taped to the floor she had to be coaxed out of calling 911.
Ellen Hendriksen (How to Be Yourself: Quiet Your Inner Critic and Rise Above Social Anxiety)
Recent magnetic resonance imaging (MRI) of dogs as they’re reunited with their owners or discover food is coming suggests that the neuro-networks that process these positive emotional experiences function similarly in them and us.

Months later, I learned that what happened that first day at restorative yoga hadn’t been entirely spiritual—I hadn’t just found the exact spot on the astral plane to tap into my sacred core. Instead, my instructor’s techniques happened to be the perfect mechanism to turn down my DMN. The default mode network is so-called because if you put people in an MRI machine for an hour and let their minds wander, the DMN is the system of connections in our brain that will light up. It’s arguably the default state of human consciousness, of boredom and daydreaming. In essence, our ego. So if you’re stuck in a machine for an hour, where does your mind go? If you’re like most people, you’ll ruminate on the past or plan your future. You might think about your relationships, upcoming errands, your zits. And scientists have found that some people who suffer from depression, anxiety, or C-PTSD have overactive DMNs. Which makes sense. The DMN is the seat of responsibility and insecurity. It can be a punishing force when it over-ruminates and gets caught in a toxic loop of obsession and self-doubt. The DMN can be silenced significantly by antidepressants or hallucinogenic substances. But the most efficient cure for an overactive DMN is mindfulness. Here’s how it works: In order for the DMN to start whirring, it needs resources to fuel its internal focus. If you’re intently focused on something external—like, say, filling out a difficult math worksheet—the brain simply doesn’t have the resources to focus internally and externally at the same time. So if you’re triggered, you can short-circuit an overactive DMN by cutting off its power source—shifting all of your brain’s energy to external stimuli instead.
Stephanie Foo (What My Bones Know: A Memoir of Healing from Complex Trauma)
Remember meditation is an active, deep remembrance, and that is discernment. Wherever you go, wherever you are, whatever you're doing, remember to utilize discernment so that you can hear and sense and feel the vibration of love rather than the vibration of illusion.

MRI machines sucked. They really, honestly sucked. You lay motionless inside a cramped metal tube that made you feel like a torpedo waiting for launch, and weird noises went off around you as you fought off claustrophobia you’d never had before for an hour that seemed to last approximately one thousand years.
Andrea Speed (Freefall (Infected, #4))
Using MRI scans, we have since looked deep into the brains of participants to see where those memories are being retrieved from before sleep relative to after sleep. It turns out that those information packets were being recalled from very different geographical locations within the brain at the two different times.
Matthew Walker (Why We Sleep: Unlocking the Power of Sleep and Dreams)
Where ego comes in, loving kindness departs. So wherever there is ego, there is very little space for true bliss and true happiness because true bliss and true happiness isn't exclusive to the attachments the ego enjoys playing with, but rather a free state of mind that is part of loving kindness and its activities inside and outside of oneself.
Tony Samara
I once asked a neuroscientist, “What’s the difference between consciousness and dreaming?” “Very little,” he told me. “In fact,” he said, “if you look at an MRI, at the actual brain processes that are happening when you are dreaming and when you are awake, they look almost identical. Only a practiced neuroscientist can tell the difference.” What

Neuroscientists have determined the brain’s dorsolateral prefrontal cortex is associated with decision making and cost-benefit assessments. If MRI brain scans had been performed on my friends and me one summer’s night when we were fifteen, they would have revealed a dark spot indicating a complete absence of activity in this region of our brains.
Ian Morgan Cron (The Road Back to You: An Enneagram Journey to Self-Discovery)
The impulse to form group identities and favor in-group members has a neurological basis. Using functional magnetic resonance imaging (fMRI), scientists have scanned people’s brains while conducting experiments similar to the one just described. Their findings, as one writer puts it, suggest that: “group identification is both innate and almost immediate.

couldn’t understand why I cried nonstop during these phone calls. I was sure that Brian had Alzheimer’s before the MRI; I’d thought, It’s not a surprise. But it was a surprise the way every bad thing, even as you see the flames in the distance, even as the terrible thing is upon you, breathing in your ear, hammering on your narrow bones, is still a surprise.

He felt the doctor’s breath on his scalp. “The bad news is that according to your MRI, that scar tissue is right here—” she tapped the very back of his skull, “in the region of your clairvoyant channel, possibly obstructing it.

why. Now she arrives at the realization that the why of evil is not to be found anywhere in the flaws of society or its institutions, nor can it be pinned down by even the most erudite and loquacious philosopher. The why of evil is in the human soul, which can’t be examined with a CT scan or MRI to locate a dark mass, or dissected in an autopsy to learn in what artery the calcification proved mortal.
Dean Koontz (The House at the End of the World)
From countless studies of MRI scans of healthy adolescents and twentysomethings, we now know that the frontal lobe does not finish wiring up until sometime between the ages of twenty and thirty. What this means is that, in our twenties, the quick, hot, impulsive, pleasure-seeking, emotional brain is ready to go, while the slow, cool, rational, forward-thinking frontal lobe is still a work in progress.
Meg Jay (The Defining Decade: Why Your Twenties Matter--And How to Make the Most of Them Now)
It might seem confusing that someone navigating toward Earth’s north pole would be attracted to the MRI’s south pole, but that’s because the Earth’s pole names are backward. The “north” end of a magnet is the one that points toward the Earth’s north pole, which means the Earth’s north magnetic pole is technically a south magnetic pole, and vice versa. This is deeply annoying to me, but there’s nothing we can do about it, so we might as well move on.
Randall Munroe (What If? 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions)
When arbitrary groups were created (such as by flipping a coin) immediately before the subject entered the MRI machine, and the hand being pricked was labeled as belonging to the same arbitrary group as the participant, even though the group hadn’t even existed just moments earlier, the participant’s brain still showed a larger spike.28 We just don’t feel as much empathy for those we see as “other.” The bottom line is that the human mind is prepared for tribalism.
Jonathan Haidt (The Coddling of the American Mind: How Good Intentions and Bad Ideas Are Setting up a Generation for Failure)
Antidepressants fail to outperform placebos in up to half of clinical trials. Armed with fMRI technology, brain scientists now understand that assuming we are born with chemical imbalances is putting the chicken before the egg—trauma changes the structure and chemical and hormonal responses of our brains. In many cases, we can’t just pump opposing chemicals into our brains with the assumption that things will change. We have to treat the underlying, original cause: the trauma.
Stephanie Foo (What My Bones Know: A Memoir of Healing from Complex Trauma)
Research shows that practices like yoga and meditation that help us to focus our attention on the present moment, are especially powerful in restructuring the brain. When new neural pathways are forged, we are able to break free of our default patterns and live more actively in a conscious state. In fact, functional MRI (fMRI) brain scans confirm this,23 showing tangible evidence that consistent consciousness practices actually thicken the prefrontal lobes, the area where our conscious awareness actually lives. Other forms of compassion-based meditation (or just closing your eyes and thinking about someone you love) help strengthen an area called the limbic system, which is the emotional center of the brain. All of this work helps to rewire our brain, disrupt our default thought patterns, and wake us up out of our subconscious-driven autopilot. From this foundation of consciousness we can then begin to witness the conditioned patterns in our thoughts, beliefs, and relationships. This honest self awareness shows us our pathway towards change and ultimately healing.
Nicole LePera (How to Do the Work: Recognize Your Patterns, Heal from Your Past, and Create Your Self)
The brain, you see, is not a computer, despite oft-repeated claims to the contrary. The brain is a living thing, much more like an overgrown garden than an orderly filing cabinet. And mind-wandering through your own garden of thoughts, memories, feelings, and desires is a sure way to discover your inner creative self. Science backs this up. Mind wandering is directly linked to enhanced creativity. The more your mind wanders, the greater the connections seen between far-flung areas of the brain on MRI exams. Daydreamers are not only more creative, they’ve even been shown to be smarter on certain tests,

Physiological confirmation of such “filling in” by involuntary musical imagery has recently been obtained by William Kelley and his colleagues at Dartmouth, who used functional MRI to scan the auditory cortex while their subjects listened to familiar and unfamiliar songs in which short segments had been replaced by gaps of silence. The silent gaps embedded in familiar songs were not consciously noticed by their subjects, but the researchers observed that these gaps “induced greater activation in the auditory association areas than did silent gaps embedded in unknown songs; this was true for gaps in songs with lyrics and without lyrics.
Oliver Sacks (Musicophilia)
This preference was vividly demonstrated in a recent fMRI study in which researchers showed seventeen Americans and seventeen Japanese pictures of men in dominance poses (arms crossed, muscles bulging, legs planted squarely on the ground) and subordinate positions (shoulders bent, hands interlocked protectively over groin, legs squeezed together tight). They found that the dominant pictures activated pleasure centers in the American brains, while the submissive pictures did the same for the Japanese. From a Western perspective, it can be hard to see what’s so attractive about submitting to the will of others. But what looks to a Westerner like subordination can seem like basic politeness to many Asians.
Susan Cain (Quiet: The Power of Introverts in a World That Can't Stop Talking)
Twentysomethings take these difficult moments particularly hard. Compared to older adults, they find negative information—the bad news—more memorable than positive information—or the good news. MRI studies show that twentysomething brains simply react more strongly to negative information than do the brains of older adults. There is more activity in the amygdala—the seat of the emotional brain. When twentysomethings have their competence criticized, they become anxious and angry. They are tempted to march in and take action. They generate negative feelings toward others and obsess about the why: “Why did my boss say that? Why doesn’t my boss like me?” Taking work so intensely personally can make a forty-hour workweek long indeed.

We went to Paris for our honey—” I trail off. God. I cannot believe I just said that out loud. He stops. “You’re telling me you dreamed about our honeymoon?” I should be too upset by what this MRI might uncover to be capable of humiliation right now, but I’m not. I feel the heat in my face and there is no way to stop it. “No comment.” He raises a brow, holding the elevator door open and following me in. “Oh, you’re not getting off that easily. If we had a honeymoon in Paris, I need to hear all about it. What did we do?” I roll my eyes, trying hard not to smile. “It was December and cold as hell, and we were there on our honeymoon. What do you think we did?” He laughs. “Wow. Any other glamorous trips where we never left the hotel?
Elizabeth O'Roark (Parallel (The Parallel Duet Book 1))
Eventually, though, my mind begins to quiet. I can feel everything slow down. I lose track of the chimes. I don’t know how many are left, and I don’t care. I focus now on a very modern kind of image: a picture of my own brain, like an fMRI, with thoughts flashing across it in angry red. As my mind slows, the red fades, and as my concentration increases, my brain begins to glow faintly white. Another unbidden thought; another trace of red that recedes like an afterimage. If it goes really well, the glow continues, and I feel the sort of exhilaration that comes when hard effort is paying off—when you reach the end of the steep trail, stand at a peak, and can see miles in every direction. But some part of me is careful not to enjoy it too much or too consciously. If I focus on it, it disappears. To sustain it, I have to just be present with it. Whether

I don't love him, though. And I don't want to be married." She stiffened slightly, and I felt her take a breath. Then she pulled a chair close to mine and sat opposite me, our hands clasped. "Every woman wants to be married, Essymay." "If that's true, then why isn't Ditte mried, or her sister? Why not Elsie or Rosfrith or Eleanor Bradley? Why not you?" "Not all women get the chance.

"But I don't want to get used to it." "What do you want?" "I want things to stay as they are. I want to keep sorting words and understanding what they mean. I want to get better at it and be given more responsibility, and I want to keep earning my own money. I feel as though I've only begun to understand who I am.

Pip Williams (The Dictionary of Lost Words)
The fact that early languages, no matter how many there are, utilize the same streams implies that the brain doesn't have a native language. The brain can only reflect the fact that a set of neural circuits was built and activated for a certain period of time. Nor does the brain care if those neural circuits map onto things that the rest of the world calls languages or dialects. It really cares only about what activates those circuits. Thus, the brain patters that typify language use across skill levels can be mapped. Brain imaging technology monitors the intensity of oxygen use around the brain - higher oxygen use represents higher energy use by cells burning glucose. The deeply engrained language circuits will create dim MRI images, because they are working efficiently, requiring less glucose overall. More recently acquired languages, as well as those used less frequently, would make neural circuits shine more brightly, because they require more brain cells, thus more glucose.

What did we talk about? I don't remember. We talked so hard and sat so still that I got cramps in my knee. We had too many cups of tea and then didn't want to leave the table to go to the bathroom because we didn't want to stop talking. You will think we talked of revolution but we didn't. Nor did we talk of our own souls. Nor of sewing. Nor of babies. Nor of departmental intrigue. It was political if by politics you mean the laboratory talk that characters in bad movies are perpetually trying to convey (unsuccessfully) when they Wrinkle Their Wee Brows and say (valiantly--dutifully--after all, they didn't write it) "But, Doctor, doesn't that violate Finagle's Constant?" I staggered to the bathroom, released floods of tea, and returned to the kitchen to talk. It was professional talk. It left my grey-faced and with such concentration that I began to develop a headache. We talked about Mary Ann Evans' loss of faith, about Emily Brontë's isolation, about Charlotte Brontë's blinding cloud, about the split in Virginia Woolf's head and the split in her economic condition. We talked about Lady Murasaki, who wrote in a form that no respectable man would touch, Hroswit, a little name whose plays "may perhaps amuse myself," Miss Austen, who had no more expression in society than a firescreen or a poker. They did not all write letters, write memoirs, or go on the stage. Sappho--only an ambiguous, somewhat disagreeable name. Corinna? The teacher of Pindar. Olive Schriener, growing up on the veldt, wrote on book, married happily, and ever wrote another. Kate Chopin wrote a scandalous book and never wrote another. (Jean has written nothing.). There was M-ry Sh-ll-y who wrote you know what and Ch-rl-tt- P-rk-ns G-lm-an, who wrote one superb horror study and lots of sludge (was it sludge?) and Ph-ll-s Wh--tl-y who was black and wrote eighteenth century odes (but it was the eighteenth century) and Mrs. -nn R-dcl-ff- S-thw-rth and Mrs. G--rg- Sh-ld-n and (Miss?) G--rg-tt- H-y-r and B-rb-r- C-rtl-nd and the legion of those, who writing, write not, like the dead Miss B--l-y of the poem who was seduced into bad practices (fudging her endings) and hanged herself in her garter. The sun was going down. I was blind and stiff. It's at this point that the computer (which has run amok and eaten Los Angeles) is defeated by some scientifically transcendent version of pulling the plug; the furniture stood around unknowing (though we had just pulled out the plug) and Lady, who got restless when people talked at suck length because she couldn't understand it, stuck her head out from under the couch, looking for things to herd. We had talked for six hours, from one in the afternoon until seven; I had at that moment an impression of our act of creation so strong, so sharp, so extraordinarily vivid, that I could not believe all our talking hadn't led to something more tangible--mightn't you expect at least a little blue pyramid sitting in the middle of the floor?

Adults can distinguish race from very minimal clues. Stanford researchers showed subjects just the front slices of plain, black profiles—the face from forehead to chin, without the hair. Subjects could tell the race of the profile (80 percent of the time) more often than they could tell the sex (70 percent), or the age within 10 years (68 percent). Race is commonly equated with skin color, but all the profiles were black. It is obviously important for adults to tell the sexes apart, but they were even better at telling races apart. Magnetic resonance imaging (MRI) has been used to determine that what is called the fusiform region of the brain may be associated with the other-race effect. The fusiform region is involved in expert appraisal. In a bird-watcher’s brain, for example, the region lights up at the sight of a bird. All people have considerable expertise in recognizing human faces, but MRI scans show greater fusiform activity—expert appraisal activity—when they are looking at faces of their own race.

Although there are no set methods to test for psychiatric disorders like psychopathy, we can determine some facets of a patient’s mental state by studying his brain with imaging techniques like PET (positron emission tomography) and fMRI (functional magnetic resonance imaging) scanning, as well as genetics, behavioral and psychometric testing, and other pieces of information gathered from a full medical and psychiatric workup. Taken together, these tests can reveal symptoms that might indicate a psychiatric disorder. Since psychiatric disorders are often characterized by more than one symptom, a patient will be diagnosed based on the number and severity of various symptoms. For most disorders, a diagnosis is also classified on a sliding scale—more often called a spectrum—that indicates whether the patient’s case is mild, moderate, or severe. The most common spectrum associated with such disorders is the autism spectrum. At the low end are delayed language learning and narrow interests, and at the high end are strongly repetitive behaviors and an inability to communicate.

MRI testing again shows what may be the underlying brain mechanism. The amygdalae are two small lobes in the brain associated with fear, arousal, and emotions. When they are active, it is thought to be a sign of vigilance, meaning that the brain is wary and wants more information. A study at Massachusetts General Hospital found that when subjects looked at photographs of faces—half were white, half were black—MRI scans found high amygdala activity. This was considered to be a normal reaction to unfamiliar faces. When the subjects looked at the photographs a second time the faces were more familiar; only the other-race faces continued to provoke high amygdala activity. This was true for both blacks and whites, suggesting that encounters with people of different races keep the brain at a higher level of watchfulness. Amygdalae notice race even when a person does not. William A. Cunningham of Ohio State University showed white subjects pictures of faces for only 30 milliseconds—not long enough for the subjects to be conscious of them—but black faces triggered greater amygdala activity than white faces. When he showed faces for a half a second—long enough for people to notice race—he found that black faces prompted greater activity in the pre-frontal areas, a part of the brain associated with detecting internal conflicts and controlling conscious behavior. This suggested the subjects were trying to suppress certain feelings about blacks. Steven Neuberg of Arizona State University attributes instinctive bias to evolution during our hunter-gatherer past. “By nature, people are group-living animals—a strategy that enhances individual survival and leads to what we might call a ‘tribal psychology’, ” he says. “It was adaptive for our ancestors to be attuned to those outside the group who posed threats such as to physical security, health or economic resources.

Yatima found verself gazing at a red-tinged cluster of pulsing organic parts, a translucent confusion of fluids and tissue. Sections divided, dissolved, reorganised. It looked like a flesher embryo – though not quite a realist portrait. The imaging technique kept changing, revealing different structures: Yatima saw hints of delicate limbs and organs caught in slices of transmitted dark; a stark silhouette of bones in an X-ray flash; the finely branched network of the nervous system bursting into view as a filigreed shadow, shrinking from myelin to lipids to a scatter of vesicled neurotransmitters against a radio-frequency MRI chirp. There were two bodies now. Twins? One was larger, though – sometimes much larger. The two kept changing places, twisting around each other, shrinking or growing in stroboscopic leaps while the wavelengths of the image stuttered across the spectrum. One flesher child was turning into a creature of glass, nerves and blood vessels vitrifying into optical fibres. A sudden, startling white-light image showed living, breathing Siamese twins, impossibly transected to expose raw pink and grey muscles working side by side with shape-memory alloys and piezoelectric actuators, flesher and gleisner anatomies interpenetrating. The scene spun and morphed into a lone robot child in a flesher's womb; spun again to show a luminous map of a citizen's mind embedded in the same woman's brain; zoomed out to place her, curled, in a cocoon of optical and electronic cables. Then a swarm of nanomachines burst through her skin, and everything scattered into a cloud of grey dust. Two flesher children walked side by side, hand in hand. Or father and son, gleisner and flesher, citizen and gleisner... Yatima gave up trying to pin them down, and let the impressions flow through ver. The figures strode calmly along a city's main street, while towers rose and crumbled around them, jungle and desert advanced and retreated. The artwork, unbidden, sent Yatima's viewpoint wheeling around the figures. Ve saw them exchanging glances, touches, kisses – and blows, awkwardly, their right arms fused at the wrists. Making peace and melting together. The smaller lifting the larger on to vis shoulders – then the passenger's height flowing down to the bearer like an hourglass's sand.

To test these ideas, Dr. Mario Beauregard of the University of Montreal recruited a group of fifteen Carmelite nuns who agreed to put their heads into an MRI machine. To qualify for the experiment, all of them must “have had an experience of intense union with God.” Originally, Dr. Beauregard had hoped that the nuns would have a mystical communion with God, which could then be recorded by an MRI scan. However, being shoved into an MRI machine, where you are surrounded by tons of magnetic coils of wire and high-tech equipment, is not an ideal setting for a religious epiphany. The best they could do was to evoke memories of previous religious experiences. “God cannot be summoned at will,” explained one of the nuns. The final result was mixed and inconclusive, but several regions of the brain clearly lit up during this experiment: •  The caudate nucleus, which is involved with learning and possibly falling in love. (Perhaps the nuns were feeling the unconditional love of God?) •  The insula, which monitors body sensations and social emotions. (Perhaps the nuns were feeling close to the other nuns as they were reaching out to God?) •  The parietal lobe, which helps process spatial awareness. (Perhaps the nuns felt they were in the physical presence of God?) Dr. Beauregard had to admit that so many areas of the brain were activated, with so many different possible interpretations, that he could not say for sure whether hyperreligiosity could be induced. However, it was clear to him that the nuns’ religious feelings were reflected in their brain scans. But did this experiment shake the nuns’ belief in God? No. In fact, the nuns concluded that God placed this “radio” in the brain so that we could communicate with Him. Their conclusion was that God created humans to have this ability, so the brain has a divine antenna given to us by God so that we can feel His presence. David Biello concludes, “Although atheists might argue that finding spirituality in the brain implies that religion is nothing more than divine delusion, the nuns were thrilled by their brain scans for precisely the opposite reason: they seemed to provide confirmation of God’s interactions with them.” Dr. Beauregard concluded, “If you are an atheist and you live a certain kind of experience, you will relate it to the magnificence of the universe. If you are a Christian, you will associate it with God. Who knows. Perhaps they are the same thing.” Similarly, Dr. Richard Dawkins, a biologist at Oxford University and an outspoken atheist, was once placed in the God helmet to see if his religious beliefs would change. They did not. So in conclusion, although hyperreligiosity may be induced via temporal lobe epilepsy and even magnetic fields, there is no convincing evidence that magnetic fields can alter one’s religious views.

As the subject watches the movies, the MRI machine creates a 3-D image of the blood flow within the brain. The MRI image looks like a vast collection of thirty thousand dots, or voxels. Each voxel represents a pinpoint of neural energy, and the color of the dot corresponds to the intensity of the signal and blood flow. Red dots represent points of large neural activity, while blue dots represent points of less activity. (The final image looks very much like thousands of Christmas lights in the shape of the brain. Immediately you can see that the brain is concentrating most of its mental energy in the visual cortex, which is located at the back of the brain, while watching these videos.) Gallant’s MRI machine is so powerful it can identify two to three hundred distinct regions of the brain and, on average, can take snapshots that have one hundred dots per region of the brain. (One goal for future generations of MRI technology is to provide an even sharper resolution by increasing the number of dots per region of the brain.) At first, this 3-D collection of colored dots looks like gibberish. But after years of research, Dr. Gallant and his colleagues have developed a mathematical formula that begins to find relationships between certain features of a picture (edges, textures, intensity, etc.) and the MRI voxels. For example, if you look at a boundary, you’ll notice it’s a region separating lighter and darker areas, and hence the edge generates a certain pattern of voxels. By having subject after subject view such a large library of movie clips, this mathematical formula is refined, allowing the computer to analyze how all sorts of images are converted into MRI voxels. Eventually the scientists were able to ascertain a direct correlation between certain MRI patterns of voxels and features within each picture. At this point, the subject is then shown another movie trailer. The computer analyzes the voxels generated during this viewing and re-creates a rough approximation of the original image. (The computer selects images from one hundred movie clips that most closely resemble the one that the subject just saw and then merges images to create a close approximation.) In this way, the computer is able to create a fuzzy video of the visual imagery going through your mind. Dr. Gallant’s mathematical formula is so versatile that it can take a collection of MRI voxels and convert it into a picture, or it can do the reverse, taking a picture and then converting it to MRI voxels. I had a chance to view the video created by Dr. Gallant’s group, and it was very impressive. Watching it was like viewing a movie with faces, animals, street scenes, and buildings through dark glasses. Although you could not see the details within each face or animal, you could clearly identify the kind of object you were seeing. Not only can this program decode what you are looking at, it can also decode imaginary images circulating in your head.

Recently, brain scans of schizophrenics taken while they were having auditory hallucinations have helped explain this ancient disorder. For example, when we silently talk to ourselves, certain parts of the brain light up on an MRI scan, especially in the temporal lobe (such as in Wernicke’s area). When a schizophrenic hears voices, the very same areas of the brain light up. The brain works hard to construct a consistent narrative, so schizophrenics try to make sense of these unauthorized voices, believing they originate from strange sources, such as Martians secretly beaming thoughts into their brains. Dr. Michael Sweeney of Ohio State writes, “Neurons wired for the sensation of sound fire on their own, like gas-soaked rags igniting spontaneously in a hot, dark garage. In the absence of sights and sounds in the surrounding environment, the schizophrenic’s brain creates a powerful illusion of reality.” Notably, these voices seem to be coming from a third party, who often gives the subject commands, which are mostly mundane but sometimes violent. Meanwhile, the simulation centers in the prefrontal cortex seem to be on automatic pilot, so in a way it’s as though the consciousness of a schizophrenic is running the same sort of simulations we all do, except they’re done without his permission. The person is literally talking to himself without his knowledge. HALLUCINATIONS The mind constantly generates hallucinations of its own, but for the most part they are easily controlled. We see images that don’t exist or hear spurious sounds, for example, so the anterior cingulate cortex is vital to distinguish the real from the manufactured. This part of the brain helps us distinguish between stimuli that are external and those that are internally generated by the mind itself. However, in schizophrenics, it is believed that this system is damaged, so that the person cannot distinguish real from imaginary voices. (The anterior cingulate cortex is vital because it lies in a strategic place, between the prefrontal cortex and the limbic system. The link between these two areas is one of the most important in the brain, since one area governs rational thinking, and the other emotions.) Hallucinations, to some extent, can be created on demand. Hallucinations occur naturally if you place someone in a pitch-black room, an isolation chamber, or a creepy environment with strange noises. These are examples of “our eyes playing tricks on us.” Actually, the brain is tricking itself, internally creating false images, trying to make sense of the world and identify threats. This effect is called “pareidolia.” Every time we look at clouds in the sky, we see images of animals, people, or our favorite cartoon characters. We have no choice. It is hardwired into our brains. In a sense, all images we see, both real and virtual, are hallucinations, because the brain is constantly creating false images to “fill in the gaps.” As we’ve seen, even real images are partly manufactured. But in the mentally ill, regions of the brain such as the anterior cingulate cortex are perhaps damaged, so the brain confuses reality and fantasy.

We are conscious of only a tiny fraction of the information that our brains process in each moment.1 Although we continually notice changes in our experience—in thought, mood, perception, behavior, etc.—we are utterly unaware of the neurophysiological events that produce them. In fact, we can be very poor witnesses to experience itself. By merely glancing at your face or listening to your tone of voice, others are often more aware of your state of mind and motivations than you are. I generally start each day with a cup of coffee or tea—sometimes two. This morning, it was coffee (two). Why not tea? I am in no position to know. I wanted coffee more than I wanted tea today, and I was free to have what I wanted. Did I consciously choose coffee over tea? No. The choice was made for me by events in my brain that I, as the conscious witness of my thoughts and actions, could not inspect or influence. Could I have “changed my mind” and switched to tea before the coffee drinker in me could get his bearings? Yes, but this impulse would also have been the product of unconscious causes. Why didn’t it arise this morning? Why might it arise in the future? I cannot know. The intention to do one thing and not another does not originate in consciousness—rather, it appears in consciousness, as does any thought or impulse that might oppose it. The physiologist Benjamin Libet famously used EEG to show that activity in the brain’s motor cortex can be detected some 300 milliseconds before a person feels that he has decided to move.2 Another lab extended this work using functional magnetic resonance imaging (fMRI): Subjects were asked to press one of two buttons while watching a “clock” composed of a random sequence of letters appearing on a screen. They reported which letter was visible at the moment they decided to press one button or the other. The experimenters found two brain regions that contained information about which button subjects would press a full 7 to 10 seconds before the decision was consciously made.3 More recently, direct recordings from the cortex showed that the activity of merely 256 neurons was sufficient to predict with 80 percent accuracy a person’s decision to move 700 milliseconds before he became aware of it.4 These findings are difficult to reconcile with the sense that we are the conscious authors of our actions. One fact now seems indisputable: Some moments before you are aware of what you will do next—a time in which you subjectively appear to have complete freedom to behave however you please—your brain has already determined what you will do. You then become conscious of this “decision” and believe that you are in the process of making it. The distinction between “higher” and “lower” systems in the brain offers no relief: I, as the conscious witness of my experience, no more initiate events in my prefrontal cortex than I cause my heart to beat. There will always be some delay between the first neurophysiological events that kindle my next conscious thought and the thought itself. And even if there weren’t—even if all mental states were truly coincident with their underlying brain states—I cannot decide what I will next think or intend until a thought or intention arises. What will my next mental state be? I do not know—it just happens. Where is the freedom in that?

For all brain tumors, definitive diagnosis can only be made by surgery with pathological examination of tissue. MRI or CT scans or other images may suggest the tumor type, but they are not definitive.

People sometimes ask what it’s like to be a surgeon who works with the living human brain each day. I think sometimes it’s like being Harry Potter—a wizard who has at his command such wonderful technologies as an MRI machine that lets us image the tissue as we remove the tumor, or a global positioning system that lets us navigate through the brain, or an operating microscope that magnifies objects forty times and lets us do very precise surgery. More often, however, it’s like Frodo Baggins in Lord of the Rings, trying to fulfill a quest against an unknown evil, surrounded by friends and working teams and helped by a little magic. You often feel vulnerable and frightened, despite a brave exterior.

Shortly after Carhart-Harris published his results in a 2012 paper in PNAS (“Neural Correlates of the Psychedelic State as Determined by fMRI Studies with Psilocybin”*), Judson Brewer, a researcher at Yale* who was using fMRI to study the brains of experienced meditators, noticed that his scans and Robin’s looked remarkably alike. The transcendence of self reported by expert meditators showed up on fMRIs as a quieting of the default mode network. It appears that when activity in the default mode network falls off precipitously, the ego temporarily vanishes, and the usual boundaries we experience between self and world, subject and object, all melt away.

When Ruth looked at the scans of her normal subjects, she found activation of DSN regions that previous researchers had described. I like to call this the Mohawk of self-awareness, the midline structures of the brain, starting out right above our eyes, running through the center of the brain all the way to the back. All these midline structures are involved in our sense of self. The largest bright region at the back of the brain is the posterior cingulate, which gives us a physical sense of where we are—our internal GPS. It is strongly connected to the medial prefrontal cortex (MPFC), the watchtower I discussed in chapter 4. (This connection doesn’t show up on the scan because the fMRI can’t measure it.) It is also connected with brain areas that register sensations coming from the rest of the body: the insula, which relays messages from the viscera to the emotional centers; the parietal lobes, which integrate sensory information; and the anterior cingulate, which coordinates emotions and thinking.

the idea of reverse inference is really not very different from the concept of decoding that was seen in the work of Jim Haxby, and you would be correct: in each case we are using neuroimaging data to try to infer the mental state of an individual. The main difference is that the reverse inference that I ridiculed from the New York Times was based not on a formal statistical model but rather on the researcher’s own judgment. However, it is possible to develop statistical models that can let us quantify exactly how well we can decode what a person is thinking about from fMRI data,

Superconductivity, since it was quantized, meaning that only discrete bundles of energy exist as opposed to a continuous flow, has not waned in importance. Once Cooper, Bardeen, and Schrieffer figured out how superconductivity worked, others were able to find useful applications for it. Superconductivity is at the heart of magnetic resonance imaging (MRI)-medical scans used to probe anatomical form and function. Some situations, such as tests for tumors, require far more precision than an X-ray scan. Strong and uniform magnetic fields are needed. The efficient electric currents in a superconductor generate the large magnetic fields, which optimize the MRI scanning operation.

In 2010 I underwent a series of MRI scans at the University of Utah. One finding was particularly gratifying. Remember that when I pointed out the size difference in my ventricles to the researchers after my first MRI, back in 1987, they told me that some asymmetry in the brain was to be expected? Well, the University of Utah study showed that my left ventricle is 57 percent longer than my right. That’s huge. In the control subjects, the difference between left and right was only 15 percent.

In 1968, elementary school teacher Jane Elliott conducted a famous experiment with her students in the days after the assassination of Dr. Martin Luther King Jr. She divided the class by eye color. The brown-eyed children were told they were better. They were the “in-group.” The blue-eyed children were told they were less than the brown-eyed children—hence becoming the “out-group.” Suddenly, former classmates who had once played happily side by side were taunting and torturing one another on the playground. Lest we assign greater morality to the “out-group,” the blue-eyed children were just as quick to attack the brown-eyed children once the roles were reversed.6 Since Elliott’s experiment, researchers have conducted thousands of studies to understand the in-group/out-group response. Now, with fMRI scans, these researchers can actually see which parts of our brains fire up when perceiving a member of an out-group. In a phenomenon called the out-group homogeneity effect, we are more likely to see members of our groups as unique and individually motivated—and more likely to see a member of the out-group as the same as everyone else in that group. When we encounter this out-group member, our amygdala—the part of our brain that processes anger and fear—is more likely to become active. The more we perceive this person outside our group as a threat, the more willing we are to treat them badly.

The notion that electromagnetic energy exists as discrete packets of energy rather than a continuous stream became the foundation on which physicists erected what is inarguably the most successful (and strangest) theory in the history of science. The laws of quantum physics not only replicate all the successes of the classical theory they supplanted (that is, a quantum calculation produces an answer at least as accurate as a classical one in problems ranging from the fall of an apple to the flight of a spaceship). They also succeed where the laws of classical physics fail. It is quantum physics, not classical physics, that explains the burning of stars, accounts for the structure of elementary particles, predicts the order of elements in the periodic table, and describes the physics of the newborn universe. Although devised to explain atomic and electromagnetic phenomena, quantum physics has “yielded a deep understanding of chemistry and the solid state,” noted the physicist Daniel Greenberger, a leading quantum theorist: quantum physics spawned quantum technologies, including transistors, lasers, semiconductors, light-emitting diodes, scans, PET scans, and MRI machines.

Diffusion tensor imaging (DTI), or tractography, is an in vivo MRI technology that uses water diffusion in brain tissue to visualize in stunning detail the brain's three-dimensional white matter anatomy. DTI is made possible by characterizing water diffusion in tissues by means of a mathematical tool called a tensor, based on matrix algebra: (1) a 3 x 3 matrix, called a diffusion tensor, is used to characterize the three-dimensional properties of water molecule diffusion; (2) from each diffusion tensor, the three pairs of eigenvalues and eigenvectors are calculated using matrix diagonalization; and (3) the eigenvector that corresponds to the largest eigenvalue is selected as the primary eigenvector. A 'streamline' algorithm then creates "tracts" by connecting adjacent voxels if their directional bias is above some treshold level. Does the orientation of the primary eigenvector coincide with that of the actual axon fibers in most white matter tracts ? Takahashi et al. (2011), for example, have demonstrated that radial organization of the subplate revealed via tractography directly correlates with its radial cellular organization, and G. Xu et al. (2014) were able to determine that transient radial coherence of white matter in the developing fetus reflected a composite of radial glial fibers, penetrating blood vessels, and radial axons.

ON THE morning of April 6, 2007, I was lying on the floor of my home office in a pool of blood. On my way down, my head had hit the corner of my desk, cutting my eye and breaking my cheekbone. I had collapsed from exhaustion and lack of sleep. In the wake of my collapse, I found myself going from doctor to doctor, from brain MRI to CAT scan to echocardiogram, to find out if there was any underlying medical problem beyond exhaustion. There wasn’t, but doctors’ waiting rooms, it turns out, were good places for me to ask myself a lot of questions about the kind of life I was living.

The oxymoronic term blindsight may seem bizarre, but it accurately describes these individuals’ Shakespearean condition: to see, but not to see. A lesion in the primary visual cortex should make a person blind, and it does deprive such patients of their conscious vision—they assure you that they cannot see anything in a specific part of the visual field (which corresponds precisely to the destroyed area of cortex), and they behave as if they were blind. Incredibly enough, however, when an experimenter shows them objects or flashes of light, they accurately point to them. 10 In a zombielike manner, they unconsciously guide their hand to locations that they do not see—blindsight indeed. Which intact anatomical pathways support unconscious vision in blindsight patients? Clearly, in these patients, some visual information still makes it through from the retina to the hand, bypassing the lesion that makes them blind. Because the entry point into the patients’ visual cortex had been destroyed, the researchers initially suspected that their unconscious behavior arose entirely from subcortical circuits. A key suspect was the superior colliculus, a nucleus in the midbrain that specializes in the cross-registration of vision, eye movements, and other spatial responses. Indeed, the first functional MRI study of blindsight demonstrated that unseen targets triggered a strong activation in the superior colliculus. 11 But that study also contained evidence that the unseen stimuli evoked activations in the cortex—and sure enough, later research confirmed that invisible stimuli could still activate both the thalamus and higher-level visual areas of the cortex, somehow bypassing the damaged primary visual area. 12 Clearly, the brain circuits that take part in our unconscious inner zombie and that guide our eye and hand movements include much more than just old subcortical routes.

STEP ONE: DECIDE & GET THE INFORMATION YOU NEED 1. Decide what you truly want for your life physically. What is the result that you’re truly after? Do you want more energy? More vitality? More strength? More flexibility? Do you want to start to rejuvenate your body? Revitalize it? Bring more youth to it? 2. Get the information that you need. Get yourself tested, so you can maximize your energy by: Knowing whether there are toxic metals in your system that are getting in the way of your well-being. Knowing if your hormones are in balance, which can make a giant difference in how you feel day to day. And then ideally, do the things that will give you peace of mind for yourself and for your family. Get the GRAIL test plus a full-body MRI so that you can know that there’s nothing to be concerned about with cancer. GRAIL can even be done even in your home, with a simple blood test. If it’s appropriate, I would consider scheduling a CCTA Test so that you know exactly where your cardiovascular health is and what needs to be done to stay strong and healthy for years to come. Consider getting the Alzheimer’s Test so that you know if you’re genetically predisposed, and also come up with a lifestyle plan that will reduce your risk. If you do this far enough in advance, there are a variety of tools in this book that can make a difference. Who’s in your family or friendship base whom you would like to also make sure gets tested to look out for their well-being and help them to maximize the quality of their life. Last, if you want to have some fun, you can discover what your true age is. As I mentioned earlier, I was thrilled to discover that my chronological age of 62 is only 51 years biologically. I think you’ll be surprised. If it’s not where you want it to be, there are so many things within these pages that you can do to change it.
