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.

It is important to note that the design of an entire brain region is simpler than the design of a single neuron. As discussed earlier, models often get simpler at a higher level—consider an analogy with a computer. We do need to understand the detailed physics ofsemiconductors to model a transistor, and the equations underlying a single real transistor are complex. A digital circuit that multiples two numbers requires hundreds of them. Yet we can model this multiplication circuit very simply with one or two formulas. An entire computer with billions of transistors can be modeled through its instruction set and register description, which can be described on a handful of written pages of text and formulas. The software programs for an operating system, language compilers, and assemblers are reasonably complex, but modeling a particular program—for example, a speech recognition programbased on hierarchical hidden Markov modeling—may likewise be described in only a few pages of equations. Nowhere in such a description would be found the details ofsemiconductor physics or even of computer architecture. A similar observation holds true for the brain. A particular neocortical pattern recognizer that detects a particular invariant visualfeature (such as a face) or that performs a bandpass filtering (restricting input to a specific frequency range) on sound or that evaluates the temporal proximity of two events can be described with far fewer specific details than the actual physics and chemicalrelations controlling the neurotransmitters, ion channels, and other synaptic and dendritic variables involved in the neural processes. Although all of this complexity needs to be carefully considered before advancing to the next higher conceptual level, much of it can be simplified as the operating principles of the brain are revealed.

It is in the nature of the human mind to give in, and hold on, to the source of solace with all the might it can muster. Life is hard and any figure that tends to ease the subjective perception of that hardship, attains a high pedestal of utmost reverence in the realm of the individual mind. It all takes place at a molecular level in the human brain with the purpose of self-preservation.

It is much easier to concentrate the mind on external things, than to concentrate on the mind itself. For example, a Neuroscientist can be the smartest man (or woman) on earth in his understanding of the human mind. He may know all the neurochemical changes underlying an outrageous behavior of a person. But when he gets mad himself, very little of his own scientific intellect would actually come in handy for him to control his rage. The virtue of self-control is a skill, which requires practice, regardless of all the neurobiological expertise in the world.

It is necessary for the future scientists interested in the field of Neurotheology, to have a bit naïve approach towards the whole idea of God and religion beyond the conventional labels of religion and atheism.

It is pretty simple - mind is a part of life - consciousness is a part of mind - God is a part of consciousness.

It is the finding of neuroscience, in fact, that belief is at least in part a matter of emotion. Whatever we believe to be true lights up areas of our brain responsible for self-identification and the processing of feelings and sentiments. If we believe something, then, the object of our belief becomes an emotionally potent aspect of our own self-image. There is some common sense to this, too: the most passionate of believers and the most strident of New Atheists are palpably, visibly fired up and ready to defend their positions.

It may seem demeaning to the vanity of some individuals, but like all elements of the mind, God and all its correlated sensations of divinity are the majestic creations of neurobiology.

It might weigh little over a kilogram but, taken on its own scale, the brain is unimaginably vast. One cubic millimetre contains between twenty and twenty-five thousand neurons. It has eighty-six billion of these cells, and each one is complex as a city and is in contact with ten thousand other neurons just like it. Within just one cubic centimetre of brain tissue, there is the same number of connections as there are stars in the Milky Way. Your brain contains a hundred trillion of them. Information in the form of electricity and chemicals flows around these paths in great forking trails and in circuits and feedback loops and fantastical storms of activity tat bloom to life speeds of up to a hundred and twenty metres per second. According to the neuroscientist V. S. Ramachandran, 'The number of permutations and combinations of activity that are theoretically possible exceeds the number of elementary particles in the universe.' And yet, he continues, 'We know so little about it that even a child's questions should be seriously entertained.

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?

It's okay to not be okay - it means that your mind is trying to heal itself.

It's simply not the case that people use one particular lobe, or a circumscribed area of the brain, to read a novel, or write an essay, or solve an equation, or calculate the angle of a triangle. And, unfortunately, neuroscience has yet to reach the stage at which it can peer into the brain and determine capacity for solving simultaneous equations or readiness to learn calculus.

Live with technology, not through technology.

I was not born with a silver spoon in my mouth, nor did I have access to information like you do today via the internet. I had to learn everything the hard way. And I had to become a scientist the old-fashioned way, which is, not through academia, but through trial and error. And my hardship opened up unforeseen gateways of perception in my mind. And through these gateways, today the whole world is able to see its inner self.

It was grace. In those who were always honest, the dlPFC, vlPFC, and ACC were in veritable comas when the chance to cheat arose. There's no conflict. There's no working hard to do the right thing. You simply don't cheat.

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

Masturbation and meditation both promote physical and mental wellbeing.

Losing connection with our loved one jeopardizes our sense of security. The alarm goes off in the brain’s amygdala, or Fear Central, as neuroscientist Joseph LeDoux of the Center for Neural Science at New York University has dubbed it. This almond-shaped area in the midbrain triggers an automatic response. We don’t think; we feel, we act.

Masturbating is no more sinful than praying or meditating.

Meditation has also been proven scientifically to untangle and rewire the neurological pathways in the brain that make up the conditioned personality. Buddhist monks, for example, have had their brains scanned by scientists as they sat still in deep altered states of consciousness invoked by transcendental meditation and the scientists were amazed at what they beheld. The frontal lobes of the monks lit up as bright as the sun! They were in states of peace and happiness the scientists had never seen before. Meditation invokes that which is known in neuroscience as neuroplasticity; which is the loosening of the old nerve cells or hardwiring in the brain, to make space for the new to emerge. Meditation, in this sense, is a fire that burns away the old or conditioned self, in the Bhagavad Gita, this is known as the Yajna; “All karma or effects of actions are completely burned away from the liberated being who, free from attachment, with his physical mind enveloped in wisdom (the higher self), performs the true spiritual fire rite.

Maybe the human brain is an object beyond the reach of metaphor, for the simple reason that it is the only object capable of creating metaphors to describe itself. There really is nothing else like it. The human brain creates the human mind, and then the human mind tries to underhand the human brain, however long it takes and whatever the cost.

Meditation is good for the elderly, great for adults, even greater for children, and greater still for pregnant women. So, meditate and be well.

Memorizing facts and then regurgitating them into carefully crafted words is not science people. It’s intellectual bulimia. Real science happens when we explore what we don’t know. The first law of understanding the human brain and the mind within, is to be an explorer.

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.

Modern society is modern because of its mental cocktail of reasoning and compassion. Turn the compassion network in the brain off, and it will be a society of heartless robots. On the other hand, turn the reasoning network off, and it will be a society of dumb sentimental apes.

Morality does not come from a book, it comes from the human mind.

More and more people will start telling themselves: "I don't understand what all these neuroexperts and consciousness philosophers are talking about, but the upshot seems pretty clear to me. The cat is out of the bag: We are gene-copying bio-robots, living out here on a lonely planet in a cold and empty physical universe. We have brains but no immortal souls, and after seventy years or so the curtain drops. There will never be an afterlife, or any kind of reward or punishment for anyone, and ultimately everyone is alone. I get the message, and you had better believe I will adjust my behavior to it. It would probably be smart not to let anybody know I've seen through the game. The most efficient strategy will be to go on pretending I'm a conservative, old-fashioned believer in moral values.

Morality does not come to this mortal world from some imaginary paradise. It rises from the neurons of mortal humans.

Most of Jesus’ life is told through the four Gospels of the New Testament, known as the Canonical gospels, written by Matthew, Mark, Luke and John. These are not biographies in the modern sense but accounts with allegorical intent. They are written to engender faith in Jesus as the Messiah and the incarnation of God, and not to provide factual data about Jesus’s life. This left the door of exaggeration open. And through that door all kinds of mystical non-sense crept in and made place right alongside the good philosophical teachings of Jesus.

Most people stand in the same place until it becomes dangerous to stay there. Then they act. Exceptional people act today to write their story.

Neurobiological differences have been demonstrated between dissociative identities within patients with DID and between patients with DID and controls. Given the current evidence, DID as a diagnostic entity cannot be explained as a phenomenon created by iatrogenic influences, suggestibility, malingering, or social role-taking. On the contrary, DID is an empirically robust chronic psychiatric disorder based on neurobiological, cognitive, and interpersonal non-integration as a response to unbearable stress. While current evidence is sufficient to firmly establish this etiological stance, given the wide opportunities for innovative research, the disorder is still understudied.

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.

Mystics would tell you, you are not your body - materialists would tell you, you are only your body - whereas the existential fact of human life is that, you are not your body - you are not your mind - you are nothing - for there is nothing constant about you at any given moment that you can say that you are that - your mind is constantly changing - your body is constantly changing - you as a bio-psychological creature are constantly evolving - if there is anything that's constant about you, it's change itself - therefore, what you really are, is an eternal force of change.

Nature, independent of mind, is devoid of both order and chaos – it is beyond the dualistic battle between order and chaos. We create our own order and chaos, based on our own knacks, desires, beliefs, biases and knowledge, and then we impose that order and chaos upon the reality that we create.

Neglect is a form of implicit abuse.

Naturalism is the least subjective reality in this human world.

Neuron is to Consciousness, what D.N.A. is to Life. Thus, Biology of Mind is to the twenty-first century, what Biology of Life was to the twentieth century.

No Scripture comes from any Supreme Creator.

One brain’s blueprint may promote joy more readily than most; in another, pessimism reigns. Whether happiness infuses or eludes a person depends, in part, on the DNA he has chanced to receive. (152)

Nothing – I repeat – nothing can become so big an obstruction in your path that you cannot overcome it, for your brain is the most divine and most godly Turing Machine of all times, capable of deeds that humanity is yet to encounter.

Often your brain makes you believe, what you see is truly real, even when it is not.

Nothing has more power over a man than a woman's tears.

[One way] researchers sometimes evaluate people's judgments is to compare those judgments with those of more mature or experienced individuals. This method has its limitations too, because mature or experienced individuals are sometimes so set in their ways that they can't properly evaluate new or unique conditions or adopt new approaches to solving problems.

One of the things that I find especially worrisome is the propensity for people to perceive reality as dyadic, comprised of two oppositional elements. Some prominent examples are our assignment of good–evil, right–wrong, just–unjust, heaven–hell, conservative–liberal, rich–poor, us–them. I also refer to this as compartmental minimalism because of our tendency to force our understanding of reality into as few categories as possible. Essentially, by perceiving reality in this way, we intentionally and unintentionally, reduce the cognitive load. We do not want the hassle of too many details or abstractions; however, this convenience comes at a cost that goes unacknowledged. We essentially build a false reality bit-by-bit.

One way or another we are all biased, but still we have the modern cortical capacity to choose whether or not to let the harmful biases dictate our behavior.

Our minds have the incredible capacity to both alter the strength of connections among neurons, essentially rewiring them, and create entirely new pathways. (It makes a computer, which cannot create new hardware when its system crashes, seem fixed and helpless).

Only the neurosurgeon dares to improve upon five billion years of evolution in a few hours. The human brain. A trillion nerve cells storing electrical patterns more numerous than the water molecules of the world’s oceans. The soul’s tapestry lies woven in the brain’s nerve threads. Delicate, inviolate, the brain floats serenely in a bone vault like the crown jewel of biology. What motivated the vast leap in intellectual horsepower between chimp and man? Between tree dweller and moon walker? Is the brain a gift from God, or simply the jackpot of a trillion rolls of DNA dice?

Our inability to understand our own minds is the price we pay for the ability to question it in the first place.

Our theoretical and practical parameters of morality are hugely based on our needs.
