“In the statistical gargon used in psychology, p refers to the probability that the difference you see between two groups (of introverts and extroverts, say, or males and females) could have occurred by chance. As a general rule, psychologists report a difference between two groups as 'significant' if the probability that it could have occurred by chance is 1 in 20, or less. The possibility of getting significant results by chance is a problem in any area of research, but it's particularly acute for sex differences research. Supppose, for example, you're a neuroscientist interested in what parts of the brain are involved in mind reading. You get fifteen participants into a scanner and ask them to guess the emotion of people in photographs. Since you have both males and females in your group, you rin a quick check to ensure that the two groups' brains respond in the same way. They do. What do you do next? Most likely, you publish your results without mentioning gender at all in your report (except to note the number of male and female participants). What you don't do is publish your findings with the title "No Sex Differences in Neural Circuitry Involved in Understanding Others' Minds." This is perfectly reasonable. After all, you weren't looking for gender difference and there were only small numbers of each sex in your study. But remember that even if males and females, overall, respond the same way on a task, five percent of studies investigating this question will throw up a "significant" difference between the sexes by chance. As Hines has explained, sex is "easily assessed, routinely evaluated, and not always reported. Because it is more interesting to find a difference than to find no difference, the 19 failures to observe a difference between men and women go unreported, whereas the 1 in 20 finding of a difference is likely to be published." This contributes to the so-called file-drawer phenomenon, whereby studies that do find sex differences get published, but those that don't languish unpublished and unseen in a researcher's file drawer.”

“My nephew has HDADHD. High Definition Attention Deficit Disorder. He can barely pay attention, but when he does it's unbelievably clear.”

Jerry A. Coyne
“Which do you think is more valuable to humanity?

a. Finding ways to tell humans that they have free will despite the incontrovertible fact that their actions are completely dictated by the laws of physics as instantiated in our bodies, brains and environments? That is, engaging in the honored philosophical practice of showing that our notion of "free will" can be compatible with determinism?


b. Telling people, based on our scientific knowledge of physics, neurology, and behavior, that our actions are predetermined rather than dictated by some ghost in our brains, and then sussing out the consequences of that conclusion and applying them to society?

Of course my answer is b).”
Jerry A. Coyne

“The spirits of the brain are directly connected to the testicles. This is why men who weary their imagination in books are less suitable for procreative functions...”

Oliver Sacks
“Some people with Tourette's have flinging tics- sudden, seemingly motiveless urges or compulsions to throw objects..... (I see somewhat similar flinging behaviors- though not tics- in my two year old godson, now in a stage of primal antinomianism and anarchy)”
Oliver Sacks, An Anthropologist on Mars: Seven Paradoxical Tales

“Nonconformists aren't just going against the grain; they're going against the brain. Either their brains aren't taking the easy way out to begin with, or in standing apart from their peers, these students are standing up to their biology.”

Abhijit Naskar
“Self is an illusory by-product of the brain's response to the environment, with the purpose of survival of life. However, within the subjective realm of the human mind, due to higher brain capacities, the self is capable of creating its own illusory purpose, in an attempt to provide meaning in life.”
Abhijit Naskar, When Humans Unite: Making A World Without Borders

Winifred Gallagher
“Recently, the search for what he calls "the splinters that make up different attention problems" has taken Castellanos in a new direction. First, he explains that your brain is far less concerned with your brilliant ideas or searing emotions than with its own internal "gyroscopic busyness," which consumes 65 percent of its total energy. Every fifty seconds, its activity fluctuates, causing what he calls a "brownout." No one knows the purpose of these neurological events, but Castellanos has a thesis: the clockwork pulses enable the brain's circuits to stay "logged on" and available to communicate with one another, even when they're not being used. "Imagine you're a cabdriver on your day off," Castellanos says. "You don't need to use your workday circuits on a Sunday, but to keep those channels open, your brain sends a ping through them every minute or so. The fluctuations are the brain's investment in maintaining its circuits online.”

“The human brain takes in information from other people and incorporates it with the information coming from its own senses, neuroscientist Gregory Berns has written. Many times, the group's opinion trumps the individual's before he even becomes aware of it.”

“The human construct of the so-called reality is prone to self−deception. One way or another, we all are being deceived by our own mind. We always see what we want to see.”

“The neurons create who you are. They create your passions. They create your ambitions. They create your unique identity, based on experiences.”
Abhijit Naskar, Wise Mating: A Treatise on Monogamy

Abhijit Naskar
“Every part of the brain plays a crucial role in the construction of something magnificent which we call ”mind”. But if we observe closely, the mind doesn’t exactly exist as one distinct process or entity or system. It’s rather an illusion. We can understand this better if we see the mind as a nation. Think of the nation you live in. Is there really any such thing as a ”nation”! A nation is simply the collection of activities of a group of people inside an imaginary border. Likewise, mind is the collection of activities of a group of neurons inside the skull. And just like in a nation, when a few neurons malfunction, others can slowly learn to take their place. But when an entire group of neurons in a specific brain region malfunctions, it can impede in the proper functioning of the mind, just like when a huge number of people in an entire state or district stop working, it can affect the functioning of the entire nation.”

“With neurology, if you go far enough with it, and you keep going, you end up getting weird. If you go a little further, you end up in the spirit.”

Olga Werby
“Our memories are not static. Each time we reach for one, we refresh and form new neuron connections, in fact changing the memory itself via our contemplation of it. Like Heisenberg Uncertainty Principle — we can observe a particle’s momentum or its position but not both simultaneously — each time we recall a particular event, we change it due to that recollection. After the mental touch, the memory is no longer the same. And this is true not just in some metaphorical sense, but in a real, tangible, physical way — the act of recall alters the neuron structures forever! And yet we eagerly recollect our favorite memories, and we just as eagerly try to forget the painful ones (and the very act of thinking of those painful memories makes them that much stronger, that much more connected and integrated into our neural memory networks).”
Olga Werby, Becoming Animals

Abhijit Naskar
“Authenticity and respect go to those who stick to their own specific field of work. For example, I am a Biologist and my work is the understanding of human nature - that's where I place all my attention. I know nothing revelatory about modern physics - I know nothing revelatory about mathematics - I know nothing revelatory about architecture - I know nothing revelatory about any field of understanding except for the ones directly related to biology. It doesn't mean that I cannot learn about other fields - I can, but every human has his or her own distinct knack, and mine is understanding humans - understanding how and why they think, what they think - how and why they feel, what they feel - how and why they behave, the way they behave - how and why they perceive, what they perceive.”
Abhijit Naskar, Monk Meets World

“neuroscience can be seen as offering metaphors that point in a general direction, but don't exactly match anyone's individual experience.”

“If the left prefrontal lobe is damaged, the patient may withdraw from the
social world and show a marked reluctance to do anything at all. This is
euphemistically called pseudodepression—“pseudo” because none of the
standard criteria for identifying depression, such as feelings of bleakness and
chronic negative thought patterns, are revealed by psychological or neurological
probing. Conversely, if the right prefrontal lobe is damaged, a patient will seem
euphoric even though, once again he really won’t be. Cases of prefrontal damage
are especially distressing to relatives. Such a patient seems to lose all interest in
his own future and he shows no moral compunctions of any kind. He may laugh
at a funeral or urinate in public. The great paradox is that he seems normal in
most respects: his language, his memory, and even his IQ are unaffected. Yet he
has lost many of the most quintessential attributes that define human nature:
ambition, empathy, foresight, a complex personality, a sense of morality, and a
sense of dignity as a human being.

For these reasons the prefrontal cortex has long
been regarded as the “seat of humanity.” As for the question of how such a
relatively small patch of the brain manages to orchestrate such a sophisticated
and elusive suite of functions, we are still very much at a loss.”

“There is little or no hope of any recovery in his memory. But a man does not consist of memory alone. He has feeling, will, sensibilities, moral being... It is here... you may touch him, and see a profound change”

“From the wheel to the steel - from papyrus to kindle - from churchbell to doorbell - from holy books to comic books - from monotheism to secularism - from fundamentalism to humanism - from steam engine to jet engine - from cave painting to apple pencil - from antibiotics to antipsychotics - from embroidery to surgery - from moving pics to netflix - every single feat that we can think of, good or bad, is born of the neurons. In short, neurons can make the world or break the world.”

“La memoria es la capacidad de seguir adelante arrastrando ciertos
aspectos de la experiencia. Incluso los músculos tienen memoria, algo que
puede apreciarse con los cambios que se producen en ellos como resultado
del ejercicio. No obstante, y más importante aún, la memoria es lo que el
cerebro hace, el modo en que nos forma, y permite que nuestro pasado ayude
a determinar nuestro futuro. En gran medida, el cerebro nos convierte en
quienes somos(...).”

“The study of how injuries in different areas of the brain result in different verbal behaviour patterns has been fundamental to relating cognitive functional models of language, informed by linguistics and cognitive psychology, with neural correlates.”
Albert Costa, The Bilingual Brain: And What It Tells Us about the Science of Language

Oliver Sacks
“I am writing this with my left hand, although I am strongly right-handed. I had surgery to my right shoulder a month ago (…) and am not capable of use of the right arm at this time. I write slowly, awkwardly – but more easily, more naturally, with each passing day. I am adapting, learning, all the while – not merely this left-handed writing, but a dozen other left-handed skills as well: I have also become very adept, prehensile, with my toes, to compensate for having one arm in a sling. (…) I am developing different patterns, different habits… a different identity, one might say. There must be changes going on with some of the programs and circuits in my brain – altering synaptic weights and connectivities and signals (though our methods of brain imaging are too crude to show these).
Nature’s imagination is richer than ours (...). For me, as a physician, nature’s richness is to be studied in the phenomena of health and disease, in the endless forms of individual adaptation by which human organisms, people, adapt and reconstruct themselves, faced with the challenges and vicissitudes of life.

Defects, disorders, diseases, in this sense, can play a paradoxical role, by bringing out latent powers, developments, evolutions, forms of life, that might never be seen, or even be imaginable, in their absence. It is the paradox of disease, in this sense, its “creative” potential, that forms the central theme of this book.

Thus while one may be horrified of the ravages of developmental disorder or disease, one may sometimes see them as creative toon- for if they destroy particular paths, they may force the nervous system into making other paths and ways, force on it an unexpected growth and evolution. This other side of development or disease is something I see, potentially, in almost every patient; and it is this, here, which I am especially concerned to describe.
In addition to the objective approach of the scientist, the naturalist, we must employ an intersubjective approach too, leaping, as Foucault writes, “into the interior of morbid consciousness [trying] to see the pathological world with the eyes of the patient himself”.
The exploration of deeply altered selves and worlds is not one that can be made in a consulting room or office. The French neurologist Francois Lhermitte is especially sensitive to this, and instead of just observing his patients in the clinic, he makes a point of visiting them at home, taking them to restaurants of theatres, or for rides in his car, sharing their lives as much as possible.”
Oliver Sacks
