All answers lie in the neurons.

All our sentiments - religious, romantic or any other - are born in the neurons.

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.

A man does not consist of memory alone. He has feeling, will, sensibility, and moral being.

Biologically speaking, you are the child of Mother Nature, and neurologically speaking, you are the heirs of immortal bliss.

Consciousness is simply the brain’s neural response to its surrounding environmental stimuli. Hence when the neural circuits malfunction, Consciousness tends to malfunction as well.

Born of neurons, soul is the very essence of being - soul is the very foundation of your existence - your psychological existence, from which all your physical prowess and progress manifest.

Brain health is not to be hailed as a habit of the rich and famous, rather it must be made a worldwide trait of human existence.

Each day I wake up with a naive perspective of life and universe, and walk towards understanding a little more about the true nature of human perception with all its vivacious nuances and behavioral expressions.

Each of us is on our own trajectory – steered by our genes and our experiences – and as a result every brain has a different internal life. Brains are as unique as snowflakes.

​God is hardwired within the neural circuitry.

...epilepsijos metu būdavo viena stadija prieš pat priepuolį (jeigu tik priepuolis ištikdavo dar su sąmone), kada staiga, užėjus liūdesiui, dvasinei tamsai, slogumui, protarpiais tarytum įsiliepsnodavo jo smegenyse ir nepaprastai įsitempdavo iš karto visos jo gyvybinės galios. Gyvybės, sąmoningumo pojūtis beveik dešimteriopai padidėdavo tomis akimirkomis, kurios praeidavo kaip žaibas. Protas, širdis nutviksdavo nepaprasta šviesa; visas jo susijaudinimas, visos dvejonės, visas nerimas tarytum nuščiūdavo iš karto, ištirpdavo kažin kokioje aukštesnėje rimtyje, sklidinoje giedro, harmoningo džiaugsmo ir vilties, sklidinoje išminties bei galutinės priežasties. Bet tokie momentai, tie pragiedruliai tik pranašaudavo tą galutinę sekundę (niekuomet ne ilgiau nei vieną sekundę), kurią prasidėdavo pats priepuolis.

​Everything that makes you, you, is a biologically existential expression of your entire brain.

Genes come together to construct a magnificent life-form, while neurons come together to form our Illusion of Consciousness.

Genetics, accidents of birth or events in early childhood have left criminals' brains and bodies with measurable flaws predisposing them to committing assault, murder and other antisocial acts. .... Many offenders also have impairments in their autonomic nervous system, the system responsible for the edgy, nervous feeling that can come with emotional arousal. This leads to a fearless, risk-taking personality, perhaps to compensate for chronic under-arousal. Many convicted criminals, like the Unabomber, have slow heartbeats. It also gives them lower heart rates, which explains why heart rate is such a good predictor of criminal tendencies. The Unabomber, Ted Kaczynski, for example, had a resting heart rate of just 54 beats per minute, which put him in the bottom 3 per cent of the population.

Even though it is common knowledge in our field of Neuroscience, I take immense pleasure every time I realize that our perception of the whole universe emerges from the activity of the little specks of jelly inside our skull.

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.

If I ask you, are you conscious right now? You'd go right ahead and tell me - yes. That's because your conscious mind is constructing an awareness in you about everything around you. And underneath that operation of your conscious mind, there are billions of neurons working in proper harmony.

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.

It's been long since thinking humanity has learnt that love is a majestic creation of the brain, yet that knowledge hasn't made love be deemed any less glorious. Then why should it threaten the religious believer to learn that divinity as well is a natural creation of the brain?

Lithium regulates the proteins that control the body’s inner clock. This clock runs, oddly, on DNA, inside special neurons deep in the brain. Special proteins attach to people’s DNA each morning, and after a fixed time they degrade and fall off. Sunlight resets the proteins over and over, so they hold on much longer. In fact, the proteins fall off only after darkness falls—at which point the brain should “notice” the bare DNA and stop producing stimulants. This process goes awry in manic-depressives because the proteins, despite the lack of sunlight, remain bound fast to their DNA. Their brains don’t realize they should stop revving. Lithium helps cleave the proteins from DNA so people can wind down. Notice that sunlight still trumps lithium during the day and resets the proteins; it’s only when the sunlight goes away at night that lithium helps DNA shake free. Far from being sunshine in a pill, then, lithium acts as “anti-sunlight.” Neurologically, it undoes sunlight and thereby compresses the circadian clock back to twenty-four hours—preventing both the mania bubble from forming and the Black Tuesday crash into depression.

Look, you can't think of a person like it's one thing, one 'I' that decides everything. The brain is a collective, a huge number of all these thinking modules. It doesn't make a decision, it arrives at one.

Memory is the binding foam of our mental life.

Memory is the coherence of life, that possesses all your emotions, and ambitions. Without it, your joyous as well as agonizing experiences of life won’t have any significance to you whatsoever.

Mother Nature created God as a neurological anti-depressant sentiment, but Man tore that God apart into pieces and made citadels of differentiation out of them.

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).

Our tests, our approaches...are ridiculously inadequate. They only show us deficits, they do not show us powers; they only show us puzzles and schemata, when we need to see music, narrative, play, a being conducting itself spontaneously in its own natural way.

Planning. Short-term memory. Attention. At first glance, these three frontal lobe functions can seem like diverse activities that just happen to be packed into the same brain region. But on closer inspection it turns out that they are facets of the same basic phenomenon of 'restraint'. Planning restrains our brains from wandering from a chosen path of activity. Short-term memory retrains sensory cortex from moving on to different imagery. Attention constrains the kind of sensory data admitted to sensory cortex.

Presiding over the entire attack there will be, in du Bois Reymond's words, "a general feeling of disorder," which may be experienced in either physical or emotional terms, and tax or elude the patient's powers of description.

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 [mental] organization of grammar [is] a case where complexity in the mind is not caused by learning; learning is caused by complexity in the mind.

The neurons create who you are. They create your passions. They create your ambitions. They create your unique identity, based on experiences.

The social environment interacts with brain chemistry. Manipulating a monkey into a lower position in the dominance hierarchy made his serotonin drop, while chemically enhancing serotonin elevated the rank of former subordinates.

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...

​The universe perceives itself through us, or to be more specific, through our neurons.

Through the sacred verses filled with violence and self-righteousness, the minds of the angry individuals find a way to get rid of all their misery. At that unstable state of consciousness, they are drawn to the description of the Holy War. They visualize a glimmer of hope. They feel absolutely immersed in it. Finally when they emerge as holy warriors, they are no longer humans, from the emotional perspective. They emerge as wild beasts, neurologically almost unable to feel human emotions, like empathy, love, kindness and compassion. Consequently the whole world faces the wrath of the most primitive of all human elements in the name of God’s judgment.

We are but a bunch of neurons.

We gain from the new science of mind not only insights into ourselves - how we perceive, learn, remember, feel, believe and act - but also a new perspective of ourselves and our fellow human beings in the context of biological evolution.

We study humans to give them a healthier and happier life.

What could we do? What should we do? 'There are no prescriptions,' Luria wrote, 'in a case like this. Do whatever your ingenuity and your heart suggest. 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 - matters of which neuropsychology cannot speak. And it is here, beyond the realm of an impersonal psychology, that you may find ways to touch him, and change him. [...] Neuropsychologically, there is little or nothing you can do; but in the realm of the Individual, there may be much you can do.

What you today perceive as beautiful and special, over time, becomes not so special. That’s how the human brain works.

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? or 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).

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.

Women, churchgoers, and conservative were more likely than men, nonchurch goers, and liberals to disagree with the reductionist (neural) account of human life.

I guess I was sad that love was not real? Or not all that real, anyway? I guess I was sad that love could feel so real and the next minute be gone, and all because of something Abnesti was doing.

In this universe, all we perceive is a virtual reality created by the neurons.

It is difficult to overstate the importance of understanding mirror neurons and their function. They may well be central to social learning, imitation, and the cultural transmission of skills and attitudes—perhaps even of the pressed-together sound clusters we call words. By hyperdeveloping the mirror-neuron system, evolution in effect turned culture into the new genome. Armed with culture, humans could adapt to hostile new environments and figure out how to exploit formerly inaccessible or poisonous food sources in just one or two generations—instead of the hundreds or thousands of generations such adaptations would have taken to accomplish through genetic evolution. Thus culture became a significant new source of evolutionary pressure, which helped select brains that had even better mirror-neuron systems and the imitative learning associated with them. The result was one of the many self-amplifying snowball effects that culminated in Homo sapiens, the ape that looked into its own mind and saw the whole cosmos reflected inside.

​I wanted to present Neuroscience to people in a way that would diminish their differences.

Naturalism is the least subjective reality in this human world.
