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.

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.

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)
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.

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.

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.

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.

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.

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)
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.

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.

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.

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.

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.

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.

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.

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)
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.

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.

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.

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.

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.

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.

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.

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.

Imagine there’s a marshmallow sitting on a plate in front of you. A nice lady in a lab coat sits next to you. She says she’s going to leave the room, and you can eat the marshmallow if you want. But if you wait for her to get back, she’ll give you two marshmallows. Oh and by the way, you’re only four years old in this scenario. So which is it: one marshmallow now or two later? Choose wisely. It may impact the rest of your life. This famous experiment was conducted over forty years ago. Kids who waited to get the second marshmallow grew up to be more successful than kids who ate the one in front of them right away. They had higher SAT scores, were more likely to go to college, and were less likely to use drugs.8 The marshmallow experiment is really a test of your prefrontal cortex’s serotonin function and its ability to override the habitual and impulsive striatum. In fact, when the kids from the original marshmallow experiment were scanned in an fMRI forty years later, they even had differences in prefrontal activity.9 The ones who had waited for the marshmallow as four-year-olds had greater ventrolateral prefrontal activity, which, unsurprisingly, helps control impulses.

I was amazed at how expensive economists thought doctors were. They instituted many economic maneuvers—de-skilling medicine onto nurses and physician assistants; computerizing medical decision-making; substituting algorithms for thinking—because they assumed that doctors were such expensive commodities. And yet doctors were not expensive, at least, not the doctors I knew. We cost no more than the nurses, the middle managers, and the information technicians, alas. Adding up all the time I spent with Mrs. Muller, the cost of her accurate diagnosis was about the same as one MRI scan, wholesale. Economists did the same thing with the other remedies of premodern medicine—good food, quiet surroundings, and the little things—treating them as expensive luxuries and cutting them out of their calculations. At Laguna Honda, for instance, while most patients were on fifteen or even twenty daily medications, many of which they didn’t need, the budget for a patient’s daily meals had been pared down to seven dollars, which could supply only the basics. I began to wonder: Had economists ever applied their standard of evidence-based medicine to their own economic assumptions? Under what conditions, with which patients and which diseases was it cost-effective to trade good food, clean surroundings, and doctor time for medications, tests, and procedures? Especially ones that patients didn’t need? Although Mrs. Muller was an impressive example of Laguna Honda’s Slow Medicine, she wasn’t the only one. Almost every patient I admitted had incorrect or outmoded diagnoses and was taking medications for them, too. Medications that required regular blood tests; caused side effects that necessitated still more medications; and put the patient at risk for adverse reactions. Typically my patients came in taking fifteen to twenty-five medications, of which they ended up needing, usually, only six or seven. And medications, even the cheapest, were expensive. Adding in the cost of side effects, lab tests, adverse reactions, and the time pharmacists, doctors, and nurses needed to prepare, order, and administer them, each medication cost something like six or seven dollars a day. So Laguna Honda’s Slow Medicine, to the extent that it led to discontinuing ten or twelve unnecessary medications, was more efficient than efficient health care by at least seventy dollars per day. I

Note: The first incident happened after the arrest by the Netherlands police in May 1980. I suffered from that, which destroyed my career, future, health, and life. I tried and tried to investigate that, but the police didn't even register the first information report (FIR). It stayed, refusing since 1980 until now, which creates suspicious questions about what the reasons are for not filing the case. It mirrors whether the Netherlands government victimised me or whether the hired ones of the international intelligence agencies have been a hindrance or the criminal groups. - The second incident happened in the shape of uncurable cancer; it was a deliberate mistake and ignorance of the Netherlands Urologists, who did not follow even the primary medical borderlines for the checkup during one year from 2016 to 2017. After the diagnosis, they are hiding the reality, and they still do not take it seriously. I still hope that the Netherlands' neutral and free media will awaken to help me investigate the incident. It will save millions of lives around the world. In God's name, take it seriously to protect me and others. I feel suspicious elements around me. I cry and pray day and night for God's protection since I do not exclude the Qadeyanis witches and magicians, who keep doing black magic continuously that the West does not understand. My Real Story In A Poem *** I never thought I would suffer from cancer The metastatic prostate gland I still cannot decide that It is natural or human-made Since everything is possible In the medical-criminal world How it happened in Western society; Civilized urologists ignored it deliberately From 2016 to 2017 Telling that nothing was wrong Whereas I was suffering from Bleeding, burning, and pain During urinating I begged urologists for a wide-scale checkup With MRI scans and other new technologies But urologists stayed rejecting; Whereas I was paying insurance for that Consequently, at the beginning of 2017 The diagnosis became a time bomb that I had metastatic prostate gland cancer, Which was not curable, They listed me on the death list, Treating for longer life expectancy However, they do tell not the truth And stay suspicious It confuses me and creates grave fear Since then I am bearing terrible side effects Factually, I became victimized twice By criminals, Intelligence Agencies And underground-mafias Which I am unable to trace alone In this regard, I approached Western Media, Ministries, police, courts, Euro Union Unfortunately, none of those responded Even my motherland media cruelly ignored It seems as if I am in the grip of the demon And The Prisoner Of The Hague Everyone has left me alone in pain, Stress, fear, depression Even my children don't care And realize my tears Where resides sympathy, empathy, And humanity? I feel death before death It is a silent cruelty Ah, where should I ask and beg For justice, help, and investigation That civilized world should know An innocent is under victimization I believe God will help and protect And someone from somewhere Appear to hold my hands To eliminate all criminals and demons My cancer will be curable With a longer life expectancy, in some ways Amen, O' merciful God amen.

need to have a prostate biopsy to confirm that the cancer recurrence is local; you will also need a bone scan and CT scan or MRI of the abdomen and pelvis to rule out the possibility that cancer has spread to distant sites. The guidelines above (see What Should I Do If My PSA Comes Back After Surgery?) may one day be adapted for men who have failed radiation treatment, but the overriding principles can be useful here in identifying the likelihood of metastases. If you have a high Gleason score (8 or greater), or if the PSA level begins to rise early after radiation therapy, or if the PSA level has a rapid doubling time, it is more likely that you have metastases than a local recurrence, and in this case, you should seek systemic therapy (see chapter 13).

that the radiation alone has not killed the cancer, this should be clear long before your PSA level reaches that point. However, it’s worth repeating that the consensus panel that developed the Phoenix definition (nadir + 2) advises, “Physicians should use individualized approaches to managing young patients with slowly rising PSA levels who initially achieved a very low nadir and who might be a candidate for salvage local therapies.” If your PSA level continues to rise, what should you do? To determine whether you are a candidate for surgery after radiation, you will need to have a prostate biopsy to confirm that the cancer recurrence is local; you will also need a bone scan and CT scan or MRI of the abdomen and pelvis to rule out the possibility that cancer has spread to distant sites.

The Happiest Man in The World The French interpreter for the 14th Dalai Lama, former academic and dedicated meditator Matthieu Ricard, came into the spotlight in the field of neural science after being named “the happiest man in the world”. Naturally, there are many other men and women who demonstrate such equanimity, but the studies on his brain uncovered truly astonishing results. MRI scans showed that Matthieu Ricard and other serious long-term meditators (with more than 10,000 hours of practice each) were mentally, emotionally and spiritually fulfilled and displayed an abundance of positive emotions and equanimity in the left pre-frontal cortex of the brain. When talking about his mindfulness training, Matthieu Ricard said with humility that: “Happiness is a skill. It requires effort and time”.

a 2007 study attempted to measure if price had any influence on the taste of wine.10 The researchers had study participants sample wine while in a functional magnetic resonance imaging (fMRI) machine. As the fMRI machine scanned the blood flow in the various regions of their brains, the tasters were informed of the cost of each wine sampled. The sample started with a $5 wine and progressed to a $90 bottle. Interestingly, as the price of the wine increased, so did the participants’ enjoyment of the wine. Not only did they say they enjoyed the wine more but their brain corroborated their feelings, showing higher spikes in the regions associated with pleasure. Little did the study participants realize that they were tasting the same wine each time.

Grouping the participants by the number of blocks they reported walking each week, the team studied participants’ initial physical assessments and then followed up with MRI scans nine years later. Four years after that, the team tested the participants for cognitive impairment and dementia. The results were impressive. Those who’d walked regularly—about six to nine miles a week—had significantly more grey matter in the frontal, occipital, and hippocampal regions than those who walked less. Checking in thirteen years after participants’ initial assessments, Erickson’s team found that those who’d logged six to nine miles a week were far less likely to be cognitively impaired than those who walked the least.

They gave nine men a combination of human growth hormone (HGH) together with DHEA (another hormone) and metformin (the diabetes drug and potential anti-aging pill you might remember from the last chapter) to combat the diabetes risk associated with HGH. The results were positive, and quite wide-ranging: their thymuses look less fatty on an MRI scan and they have more T cells fresh from the thymus, as you’d hope—but they also saw improvements in kidney function and, most excitingly, a reduction in their epigenetic age, as measured by the morbidly accurate epigenetic clocks we met a couple of chapters ago. This suggests that rejuvenating the thymus can go on to rejuvenate the body more generally, not just the immune system—and, given the immune system’s wide remit for defense and maintenance around the body, perhaps this shouldn’t come as a surprise.

For example, in the past, it was revealed that the actor Dick Van Dyke had experienced severe headaches that affected his sleep and caused chronic fatigue. Over a seven-year period, he saw a number of different healthcare professionals, received a CAT scan, MRI, and a spinal tap, along with other tests, but everything came back negative. It wasn’t until his dental implants were removed that he finally received relief from his symptoms.

For example, the diagnostic study (CT scan or MRI) might show a herniated disc at the interspace L4-L5, one of the possible consequences of which might be weakness in the muscles that elevate the foot and the toes. The examination, however, revealed that not only those muscles were weak but so were the ones in the back of the leg, muscles that are not energized by the spinal nerve passing by interspace L4-L5. Then when I found on examination that the buttock muscles in the vicinity of the sciatic nerve were painful to pressure, it was apparent that the nerve disturbance was not coming from the region of the herniated disc but from the sciatic nerve that serves both sets of muscles.

This ability to change the brain’s wiring, to grow new neural connections, has been demonstrated in experiments such as one conducted by Doctors Avi Karni and Leslie Underleider at the National Institutes of Mental Health. In that experiment, the researchers had subjects perform a simple motor task, a finger-tapping exercise, and identified the parts of the brain involved in the task by taking a MRI brain scan. The subjects then practiced the finger exercise daily for four weeks, gradually becoming more efficient and quicker at it. At the end of the four-week period, the brain scan was repeated and showed that the area of the brain involved in the task had expanded; this indicated that the regular practice and repetition of the task had recruited new nerve cells and changed the neural connections that had originally been involved in the task.

This remarkable feature of the brain appears to be the physiological basis for the possibility of transforming our minds. By mobilizing our thoughts and practicing new ways of thinking, we can reshape our nerve cells and change the way our brains work. It is also the basis for the idea that inner transformation begins with learning (new input) and involves the discipline of gradually replacing our “negative conditioning” (corresponding with our present characteristic nerve cell activation patterns) with “positive conditioning” (forming new neural circuits). Thus, the idea of training the mind for happiness becomes a very real possibility.

Do you wonder whether we’re living in a dystopian future when Gopi Kallayil, a chief evangelist at Google, refers to our smartphones as our “seventy-ninth organ”? Is it even scarier now that MRI scans have revealed that the gray matter in a phone addict’s brain physically changes shape and size similar to a drug user’s brain? Personally, if I’m going to have a phone, I’d rather have it as a tool than as a brain-altering appendage.

When we were seated again in his office, he handed me a copy of the newly published paper. Only forty-four people with schizophrenia participated in the trial, but small as it was, there was nothing ambiguous about the results. Based on MRI scans, twelve of them had missing gray matter in parts of their cerebral cortex—a puzzling but not uncommon feature of the disease—and they alone had the parasite. I shot him a raised-eyebrow look that said Yikes! and he replied, “Jiří had the same response.

The journaling helps because your brain stores trauma, unfinished actions, and powerful memories in areas that can trigger strong emotions and subconscious stress responses. Often these unresolved events can trigger anxiety for no apparent reason. When you convert your feelings into words, it prompts a neurologic change. MRI scans have proven that the act of speaking or writing about feelings that are top of mind can move stored experiences away from the emotional reptilian parts of the brain, where they continually recirculate up to the rational parts of the brain, where they begin to dissipate. This effect can be invoked any time you convert ideas into words, regardless of whether you are speaking, writing, or typing and regardless of any feedback you receive.

A coaching session can be compared to the creative process of freestyle rap. Neuroscientists at the National Institute on Deafness and Other Communication Disorders scanned the brains of twelve professional rappers with an fMRI (functional magnetic resonance imaging) machine. The scientists discovered that although the brain’s executive functions were active at the start and end of a song, during freestyle, the parts of the brain responsible for self-monitoring, critiquing, and editing were deactivated. In this context, the researchers explained that the rappers were “freed from the conventional constraints of supervisory attention and executive control,” so sudden insights could easily emerge.1 In other words, the rappers used the executive functions of their cognitive brains as they started rapping to deliberately set the intention of the composition up front. Once they had a sense of where they were going, they switched off their inner critic and analyzer. This allowed for more activity in the inner brain, where the eruption of new ideas—creativity—takes place. As they moved to closing out the song, their cognitive brains came back online to provide a consciously designed ending to the composition.

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.

was exploring something called Decoded Neurofeedback. It resembled old-fashioned biofeedback, but with neural imaging for real-time, AI-mediated feedback. A first group of subjects—the “targets”—entered emotional states in response to external prompts, while researchers scanned relevant regions of their brains using fMRI. The researchers then scanned the same brain regions of a second group of subjects—the “trainees”—in real time. AI monitored the neural activity and sent auditory and visual cues to steer the trainees toward the targets’ prerecorded neural states. In this way, the trainees learned to approximate the patterns of excitation in the targets’ brains, and, remarkably, began to report having similar emotions. The technique dated back to 2011, and it claimed some impressive early results. Teams in Boston and Japan taught trainees to solve visual puzzles faster, simply by training them on the visual cortex patterns of targets who’d learned the puzzles by trial and error. Other experimenters recorded the visual fields of target subjects exposed to the color red. Trainees who learned, through feedback, to approximate that same neural activity reported seeing red in their mind’s eye. Since those days, the field had shifted from visual learning to emotional conditioning. The big grant money was going to desensitizing people with PTSD. DecNef and Connectivity Feedback were being touted as treatments to all kinds of psychiatric disorders. Marty Currier worked on clinical applications. But he was also pursuing

I anticipate diagnostic AI will exceed all but the best doctors in the next twenty years. This trend will be felt first in fields like radiology, where computer-vision algorithms are already more accurate than good radiologists for certain types of MRI and CT scans. In the story “Contactless Love,” we see that by 2041 radiologists’ jobs will be mostly taken over by AI. Alongside radiology, we will also see AI excel in pathology and diagnostic ophthalmology. Diagnostic AI for general practitioners will emerge later, one disease at a time, gradually covering all diagnoses. Because human lives are at stake, AI will first serve as a tool within doctors’ disposal or will be deployed only in situations where a human doctor is unavailable. But over time, when trained on more data, AI will become so good that most doctors will be routinely rubber-stamping AI diagnoses, while the human doctors themselves are transformed into something akin to compassionate caregivers and medical communicators.

When these ancient parts of your brain are active or rehearsing the next disaster using the DMN, they effortlessly hijack your attention. You try to meditate and repetitive negative thinking takes over. In the cage match between Caveman Brain and Bliss Brain, Caveman Brain always wins. Survival is a more important need than happiness or self-actualization. You can’t self-actualize if you’re dead. In 2015 the US National Institutes of Health estimated that less than 10% of the US population meditates. One of the primary reasons for this is that meditation is hard. Most people who start a meditation program drop out. GETTING THE BEST OF ALL WORLDS When writing my first best-selling book, The Genie in Your Genes, I experimented with many schools of stress reduction and meditation. Heart coherence. Mindfulness. EFT tapping. Neurofeedback. Hypnosis. One day I had a Big Idea: What happens when you combine them all? I began playing with a routine that did just that. Here’s what I came up with: First, you tap on acupressure points to relieve stress. Second, you close your eyes and relax your tongue on the floor of your mouth. This sends a signal to your vagus nerve, which wanders all over your body, connecting all the major organ systems. It’s the key signaling component of the parasympathetic nervous system, which governs relaxation. 4.8. The vagus nerve connects with all the major organ systems of your body. Third, you imagine the volume of space inside your body, particularly between your eyes. This automatically generates big alpha in your brain, moving you toward the Awakened Mind. Fourth, you slow your breathing down to 6 seconds per inbreath and 6 seconds per outbreath. This puts you into heart coherence. Fifth, you imagine your breath coming in and going out from your heart area, and you picture a sphere of energy in your heart. Sixth, you send a beam of heart energy to a person or place that makes you feel wonderful. This puts you into deep coherence. After enjoying the connection for a while, you send compassion to everyone and everything in the universe. Feeling universal compassion produces the major brain changes seen in fMRI scans of longtime meditators. As we’ll see in Chapters 6 and 8, compassion moves the needle like nothing else. At this point, most people drop into Bliss Brain automatically. They’re in a combination of alpha, heart coherence, and parasympathetic dominance. They haven’t been asked to still their minds, sit cross-legged, follow a guru, or believe in a deity. They’ve just followed a sequence of simple physical steps. After a few minutes of universal compassion, you again focus your beam on a single person or place. You then gently disengage and draw the energy beam back into your own heart. Seventh, you direct your beam of compassion to a part of your body that is suffering or in pain. You end the meditation by returning your attention to the here and now.

Why Women Are Wonderful Listeners In general, women are excellent listeners already. When a woman communicates, according to MRI scans, fully seven centers of her brain are involved. In men, it is only two. Men often listen halfheartedly to women, especially if the television is on. That’s because men can only process one sensory input at a time. They cannot, for example, both watch television and listen to someone else speaking, which women can do much more easily.

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.

The majority of Lyme patients I see in my practice have peripheral neuropathy. It presents as burning sensations in different parts of the body, or tingling and numbness that often comes and goes. Patients usually describe this in the upper and lower extremities, and often on their face and scalp. Many patients have gone to the emergency room for a CAT scan of the head or an MRI of the brain to rule out a transient ischemic attack (TIA) or stroke/cerebrovascular accident (CVA), since they had numbness, which was new or increased, in one part of their body. The doctors would rule out a TIA or stroke and send them home without a diagnosis, often telling them to follow up with their primary care physician and a neurologist.
