Because what we associate with the idea of love is purely chemical. It can be broken down into scientifically proven phases: it starts with a dose of testosterone and estrogen, what we would think of as ‘lust,’ followed by the goofy ‘lovesick’ phase, which is a combination of adrenaline, dopamine, and a drop in serotonin levels—which, by the way, makes our brains behave exactly like the brains of crack addicts—and ends up, if we make it through phases one and two, with ‘attachment,’ where the body produces oxytocin and vasopressin, which basically make us want to cuddle excessively. It’s science. That’s all.
Cynthia Hand (The Last Time We Say Goodbye)
The more a sufferer concentrates on his symptoms, the deeper those symptoms are etched into his neural circuits. In the worst cases, the mind essentially trains itself to be sick. Many addictions, too, are reinforced by the strengthening of plastic pathways to the brain. Even very small doses of addictive drugs can dramatically alter the flow of neurotransmitters in a person’s synapses, resulting in long-lasting alterations in brain circuitry and function. In some cases, the buildup of certain kinds of neurotransmitters, such as dopamine, a pleasure-producing cousin to adrenaline, seems to actually trigger the turning on or off particular genes, bringing even stronger cravings for the drug. The vital path turns deadly.
Nicholas Carr (What the Internet is Doing to Our Brains)
Conspiracy theories are really attractive. Figuring out patterns is one of the things that gets your brain to give you a nice dose of chemical reward, the little ping of dopamine and whatever else that keeps you smiling. As a result, your brain is pretty good at finding patterns, and at disregarding information that doesn’t fit. Which means it’s also pretty good at finding false patterns, and at confirmation bias, and a bunch of other things that can be fatal. Our brains are also really good at making us the center of a narrative, because it’s what we evolved for.
Elizabeth Bear (Ancestral Night (White Space, #1))
Needing more of a substance to feel pleasure, or experiencing less pleasure at a given dose, is called tolerance. Tolerance is an important factor in the development of addiction.
Anna Lembke (Dopamine Nation: Finding Balance in the Age of Indulgence)
People who live with ADHD are at high risk of addiction, especially adolescents, because of their poorly functioning frontal lobes. Years ago, when the illness was less well understood, doctors and parents were reluctant to give these vulnerable children addictive drugs such as Ritalin and amphetamine. It sounded reasonable: don’t give addictive substances to people at risk for addiction. But rigorous testing showed unambiguously that adolescents who were treated with stimulant drugs were less likely to develop addictions. In fact, those who started the drug at the youngest age and took the highest doses were the least likely to develop problems with illicit drugs. Here’s why: if you strengthen the dopamine control circuit, it’s a lot easier to make wise decisions. On the other hand, if effective treatment is withheld, the weakness of the control circuit is not corrected. The desire circuit acts unopposed, increasing the likelihood of high-risk, pleasure-seeking behavior.
Daniel Z. Lieberman (The Molecule of More: How a Single Chemical in Your Brain Drives Love, Sex, and Creativity―and Will Determine the Fate of the Human Race)
Why does chronic self-administration of cocaine reduce the density of dopamine receptors? It’s a simple matter of brain economics. The brain is accustomed to a certain level of dopamine activity. If it is flooded with artificially high dopamine levels, it seeks to restore the equilibrium by reducing the number of receptors where the dopamine can act. This mechanism helps to explain the phenomenon of tolerance, by which the user has to inject, ingest, or inhale higher and higher doses of a substance to get the same effect as before.

Dave Asprey (Super Human: The Bulletproof Plan to Age Backward and Maybe Even Live Forever)
There is only one historical development that has real significance. Today, when we finally realise that the keys to happiness are in the hands of our biochemical system, we can stop wasting our time on politics and social reforms, putsches and ideologies, and focus instead on the only thing that can make us truly happy: manipulating our biochemistry. If we invest billions in understanding our brain chemistry and developing appropriate treatments, we can make people far happier than ever before, without any need of revolutions. Prozac, for example, does not change regimes, but by raising serotonin levels it lifts people out of their depression. Nothing captures the biological argument better than the famous New Age slogan: ‘Happiness begins within.’ Money, social status, plastic surgery, beautiful houses, powerful positions – none of these will bring you happiness. Lasting happiness comes only from serotonin, dopamine and oxytocin.1 In Aldous Huxley’s dystopian novel Brave New World, published in 1932 at the height of the Great Depression, happiness is the supreme value and psychiatric drugs replace the police and the ballot as the foundation of politics. Every day, each person takes a dose of ‘soma’, a synthetic drug which makes people happy without harming their productivity and efficiency. The World State that governs the entire globe is never threatened by wars, revolutions, strikes or demonstrations, because all people are supremely content with their current conditions, whatever they may be. Huxley’s vision of the future is far more troubling than George Orwell’s Nineteen Eighty-Four. Huxley’s world seems monstrous to most readers, but it is hard to explain why. Everybody is happy all the time – what could be wrong with that?
Yuval Noah Harari (Sapiens: A Brief History of Humankind)
Dopamine enhances the ability of neurons to transmit signals between one another. How? By acting as an agonist (as opposed to antagonist), or a substance that enhances neural activity. Dopamine binds to specific receptor molecule sites on the synaptic clefts of the neurons, as if it were the CTS that normally bind there.12 It increases the rate of neural firing in association with pattern recognition, which means that synaptic connections between neurons are likely to increase in response to a perceived pattern, thereby cementing those perceived patterns into long-term memory through the actual physical growth of new neural connections and the reinforcement of old synaptic links. Increasing dopamine increases pattern detection; scientists have found that dopamine agonists not only enhance learning but in higher doses can also trigger symptoms of psychosis, such as hallucinations, which may be related to that fine line between creativity (discriminate patternicity) and madness (indiscriminate patternicity). The dose is the key. Too much of it and you are likely to be making lots of Type I errors—false positives—in which you find connections that are not really there. Too little and you make Type II errors—false negatives—in which you miss connections that are real.
Michael Shermer (The Believing Brain: From Ghosts and Gods to Politics and Conspiracies How We Construct Beliefs and Reinforce Them as Truths)
In addiction, this means that because being addicted escalates wanting more than liking, the drug experience gets deeply carved into your memory. Anything you can associate with achieving a drug high, you will. As a result, when you try to quit, everything from a spoon (you could use it to prepare drugs) to a street (this is where the dealer lives!) to stress (when I feel like this, I need drugs) can come to drive craving. Desire fuels learning, whether it is normal learning or the pathological “overlearning” that occurs in addiction. You learn what interests you with ease because desire motivates. In contrast, it’s far more difficult to learn something you don’t want to understand or care to comprehend. Berridge and Robinson’s research also helps resolve another paradox: If dopamine signifies pleasure, then the brain should become less and less responsive to it as tolerance to a drug develops. But while tolerance clearly does occur, the opposite result is also seen in the brain. As I took cocaine, paranoia began to set in at lower and lower doses—not higher ones. The summer of 1988, it also took increasingly less drug to achieve the state of heart-pounding anxiety and mortal dread that I experienced so frequently. Neuroscientist Marc Lewis described his experience of this effect in his addiction memoir this way: “I kept pumping [cocaine] into my vein, this non-sterile solution, until my reeling consciousness, nausea, racing heart, and bloated capillaries told me that death was near. Later that night, I begged myself to stop.… But the urge would not relent.
Maia Szalavitz (Unbroken Brain: A Revolutionary New Way of Understanding Addiction)
D.O.S.E meaning the natural production of ‘feel-good’ brain chemicals such as: --Dopamine (responsible for intense pleasure.) --Oxytocin (known as the love hormone.) --Serotonin (a natural mood enhancer.) --Endorphins (a natural pain-killer).
M.P. Neary (Free Your Mind)
HH Dalai Lama: Some forms of meditation are very difficult. One of my close friends was a very good meditator who attempted to cultivate single-pointedness of mind. He had the experience of spending a few years in a Chinese prison, and he told me that the meditation was actually harder than being a prisoner. The point is that he had to be constantly aware and attentive without losing his attention even for a moment. A constant vigilance was required. One factor that needs to be taken into account is the intensity and quality of the meditator’s motivation. In the traditional Buddhist context, meditators are highly motivated individuals who have a deep appreciation of the framework of the Buddhist path and an understanding of its causes and effects: If I do this, this will happen. They understand the nature of the path and its culmination. There is a deep recognition that the fulfillment of one’s aspiration for happiness really lies in the transformation of one’s undisciplined state to a more disciplined state of mind. These individuals take into account all of this context, so when they engage in meditation, they have a tremendous sense of dedication, joy, a very strong motivation, and sustained enthusiasm. But if you just tell a child, with no context at all, to start meditating, there will be no incentive, no inspiration. Robert, you made the comment that in small doses, stress can actually raise dopamine levels, which we assume corresponds in the rat to a heightened sense of well-being or pleasure. I wonder whether there might be an analogue in meditation, specifically in the training of single-pointed attention, or samadhi, which is not uniquely Buddhist. As one trains incrementally in developing attention, a quality arises that is described as suppleness or malleability of the body and mind, and is often conjoined with a sense of well-being, perhaps even bliss. It happens very strongly when one achieves a high state of samadhi, but even incrementally along the path, there are many surges of this type of malleability together with a kind of bliss. This may be an interesting area of research, to see from the neurophysiological perspective what some of the unexpected events are that come out of such attentional training.

Now that you’ve received your dose of stimulation, you can work, right? But what happens when you sit at your desk to work on an important project? Does it come easy, or do you feel like doing everything else but working? Perhaps you tell yourself you can work on that particular task later. Perhaps you suddenly fancy another cup of coffee or perhaps you just remembered the email you need to answer.
Thibaut Meurisse (Dopamine Detox : A Short Guide to Remove Distractions and Get Your Brain to Do Hard Things (Productivity Series Book 1))
What was love anyway, except a biological trick? It was larger doses of hormones like oxytocin and dopamine, which delivered a euphoric rush. It was lower levels of serotonin, which induced anxiety and made you focus obsessively on the object of your “love.” It was elevated levels of adrenaline and norepinephrine making your heart flutter and your palms sweat. She liked Joe and he liked her. The rest was a temporary chemical imbalance.
Monica Ali (Love Marriage)
This hijacking of the brain’s attention by an overload of social stimulation engages the same chemical pathways of reward as do such drugs as caffeine, nicotine, cocaine, and the amphetamines. Drugs with abuse potential short-circuit and amplify the rewarding dopamine responses to normal social interactions by blocking the dopamine-recycling systems that balance dopamine with the other chemical messengers, such as serotonin, and protect the brain from excess stimulation. Cocaine or amphetamines, for example, when taken in small doses induce the rush of an immediate and pleasurable high. But with repeated use or excessive dose, the pleasure dissolves into a dysphoric and dangerous, drug-driven mania. From
Peter C. Whybrow (American Mania: When More is Not Enough)
I explained to her that any drug that stimulates our reward pathway the way cannabis does has the potential to change our brain’s baseline anxiety. What feels like cannabis treating anxiety may in fact be cannabis relieving withdrawal from our last dose. Cannabis becomes the cause of our anxiety rather than the cure.
Anna Lembke (Dopamine Nation: Finding Balance in the Age of Indulgence)
Norepinephrine: The Wake-Up Neurotransmitter One of norepinephrine’s effects on the brain is to sharpen attention. As we saw earlier, norepinephrine (aka noradrenaline) can function as both a neurotransmitter and a hormone. When we perceive stress and activate the fight-or-flight response, the brain produces bursts of norepinephrine, triggering anxiety. But sustained and moderate secretion can also produce a beneficial result in the form of heightened attention, even euphoria, and meditation has been shown to produce a rise in norepinephrine in the brain. A modest dose of norepinephrine is also associated with reduced beta brain waves. 5.11. Norepinephrine: your wake-up molecule. Notice the paradox here. Norepinephrine is associated with both anxiety and attentiveness. How do you get enough to be alert, but not so much you’re stressed? Surrender is the key. Steven Kotler, co-author of Stealing Fire, says that stress neurochemicals like norepinephrine actually prime the brain for flow states. At first, the meditator is frustrated by Monkey Mind. But if she surrenders, despite the perpetual self-chatter of the DMN, she enters the next phase of flow, which is focus. She has hacked her biology, using the negative experience of mind wandering as a springboard to flow. Norepinephrine’s molecular structure is similar to its cousin, epinephrine. While epinephrine works on a number of sites in the body, norepinephrine works exclusively on the arteries. When both dopamine and norepinephrine are present in the brain at the same time, they amplify focus. Attention becomes sharp, while perception is enhanced. Staying alert is a key function of the brain’s attention circuit, which keeps you focused on the object of your meditation and counteracts the wandering mind. It also stops you from becoming drowsy, an occupational hazard for meditators. That’s because pleasure neurotransmitters such as serotonin and melatonin (for which serotonin is the precursor) can put you to sleep if not balanced by alertness-producing norepinephrine. Again, the ratios are the key. Oxytocin: The Hug Drug 5.12. Oxytocin: your cuddle molecule. Oxytocin is produced by the hypothalamus, part of the brain’s limbic system. When activated, neurons in the hypothalamus stimulate the pituitary gland to release oxytocin into the bloodstream. So even though oxytocin is produced in the brain, it has effects on the body as well, giving it the status of a hormone. It is one of a group of small protein molecules called neuropeptides. A closely related neuropeptide is vasopressin. All mammals produce some variant of these neuropeptides. Oxytocin promotes bonding between humans. It is responsible for maternal feelings and physically prepares the female body for childbirth and nursing. It is generated through physical touch but also by emotional intimacy. Oxytocin also facilitates generosity and trust within a group. Oxytocin is the hormone associated with the long slow waves of delta. A researcher hooking subjects up to an EEG found that touch stimulated greater amounts of delta, with certain regions of the skin being more sensitive. The biggest effect was produced by tapping the cheek, as we do in EFT. It produced an 800% spike in delta.
Dawson Church (Bliss Brain: The Neuroscience of Remodeling Your Brain for Resilience, Creativity, and Joy)
There are four primary chemicals in our body that contribute to all our positive feelings that I will generically call “happy”: endorphins, dopamine, serotonin and oxytocin. Whether acting alone or in concert, in small doses or large, anytime we feel any sense of happiness or joy, odds are it is because one or more of these chemicals is coursing through our veins. They do not exist simply to make us feel good.
Simon Sinek (Leaders Eat Last: Why Some Teams Pull Together and Others Don't)
It has been well established that television, films, and magazines distort people’s standards and perception of beauty.748 The photoshopped and filtered photos online and in magazines create an unrealistic expectation of beauty that is unattainable by anyone.749 Pornography has even more devastating effects on viewers. Watching porn literally rewires the brain in what is called neuroplastic change, and gradually affects the release of dopamine. Psychiatrist Norman Doidge says, “Because plasticity is competitive, the brain maps for new, exciting images increased at the expense of what had previously attracted them.”750 What this means is that frequent porn watchers develop a “tolerance” similar to drug users, and then require harder (and weirder) porn in order for the same amount of dopamine to be released.751 Many regular porn watchers become unable to maintain erections during sex with an actual person, similar to how a drug addict is unable to get a good buzz from an average dose of whatever their drug of choice is.
Mark Dice (The Illuminati in Hollywood: Celebrities, Conspiracies, and Secret Societies in Pop Culture and the Entertainment Industry)
In the Redish model, the excess dopamine provides additional value, no matter what. Marks et al. (2010) directly tested this hypothesis in an elegant experiment, where rats were trained to press two levers for a certain dose of cocaine (both levers being equal). One lever was then removed and the other provided smaller doses of cocaine. The Redish theory predicts that the second lever should gain value, while expectation of homeostatis theories would predict that the second lever should lose value (because animals would learn the second lever was providing smaller doses). The Marks et al. data was not consistent with the Redish excess-delta model. However, a key factor in drug addiction is that not everyone who takes drugs loses control over their drug use and becomes an addict. Studies of drug use in both human and nonhuman animals suggest that most animals in self-administration experiments continue to show elasticity in drug-taking, stopping in response to high cost, but that a small proportion (interestingly similar to the proportion of humans who become addicted to drugs) become inelastic to drug-taking, being willing to pay excessive costs for their drugs. One possibility is that the homeostatic models are a good description of nonaddicted animals, which have a goal of maintaining a satiety level, but that addiction is different.
