“It was Freud's ambition to discover the cause of hysteria, the archetypal female neurosis of his time. In his early investigations, he gained the trust and confidence of many women, who revealed their troubles to him.Time after time, Freud's patients, women from prosperous, conventional families, unburdened painful memories of childhood sexual encounters with men they had trusted: family friends, relatives, and fathers. Freud initially believed his patients and recognized the significance of their confessions. In 1896, with the publication of two works, The Aetiology of Hysteria and Studies on Hysteria, he announced that he had solved the mystery of the female neurosis. At the origin of every case of hysteria, Freud asserted, was a childhood sexual trauma. But Freud was never comfortable with this discovery, because of what it implied about the behavior of respectable family men. If his patients' reports were true, incest was not a rare abuse, confined to the poor and the mentally defective, but was endemic to the patriarchal family. Recognizing the implicit challenge to patriarchal values, Freud refused to identify fathers publicly as sexual aggressors. Though in his private correspondence he cited "seduction by the father" as the "essential point" in hysteria, he was never able to bring himself to make this statement in public. Scrupulously honest and courageous in other respects, Freud falsified his incest cases. In The Aetiology of Hysteria, Freud implausibly identified governessss, nurses, maids, and children of both sexes as the offenders. In Studies in Hysteria, he managed to name an uncle as the seducer in two cases. Many years later, Freud acknowledged that the "uncles" who had molested Rosaslia and Katharina were in fact their fathers. Though he had shown little reluctance to shock prudish sensibilities in other matters, Freud claimed that "discretion" had led him to suppress this essential information. Even though Freud had gone to such lengths to avoid publicly inculpating fathers, he remained so distressed by his seduction theory that within a year he repudiated it entirely. He concluded that his patients' numerous reports of sexual abuse were untrue. This conclusion was based not on any new evidence from patients, but rather on Freud's own growing unwillingness to believe that licentious behavior on the part of fathers could be so widespread. His correspondence of the period revealed that he was particularly troubled by awareness of his own incestuous wishes toward his daughter, and by suspicions of his father, who had died recently. p9-10”

“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.”

“For many years, it was believed that the connections between neurons in an adult brain were fixed. Learning, it was believed, involved increasing or decreasing the strength of synapses. This is still how learning occurs in most artificial neural networks. However, over the past few decades, scientists have discovered that in many parts of the brain, including the neocortex, new synapses form and old ones disappear. Every day, many of the synapses on an individual neuron will disappear and new ones will replace them. Thus, much of learning occurs by forming new connections between neurons that were previously not connected. Forgetting happens when old or unused connections are removed entirely.”

“At this moment, in this place, the shifting action potential in my neurons cascade into certain arrangements, patterns, thoughts; they flow down my spine, branch into my arms, my fingers, until muscles twitch and thought is translated into motion; mechanical levers are pressed; electrons are rearranged; marks are made on paper. At another time, in another place, light strikes the marks, reflects into a pair of high-precision optical instruments sculpted by nature after billions of years of random mutations; upside-down images are formed against two screens made up of millions of light-sensitive cells, which translate light into electrical pulses that go up the optic nerves, cross the chiasm, down the optic tracts, and into the visual cortex, where the pulses are reassembled into letters, punctuation marks, words, sentences, vehicles, tenors, thoughts. The entire system seems fragile, preposterous, science fictional.”

“Consistent and chronic distractions have the power we give it focal access, to rob us of our long-term historic memory of unhurried moments in life where we are divinely invited to experience that which is the lovely, praiseworthy and excellent...give heed to the call of voices in a song that raises the vibration of a melodic verses, in such a spectacular way, that our neurons create a bio-celluar concert to revive the soul of our best memories. . .selah”

“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.”

“Imagine: inside, in the nerves, in the head―that is, these nerves are there in the brain... (damn them!) there are sort of little tails, the little tails of those nerves, and as soon as they begin quivering... that is, you see, I took at something with my eyes and begin quivering, those little tails... and when they quiver, then an image appears... it doesn't appear at once, but an instant, a second, passes... and then something like a moment appears; that is, not a moment―devil take the moment!―but an image; that is, an object, or an action, damn it! That's why I see and then think, because of those tails, not because I've got a soul, and that I am some sort of image and likeness. All that is nonsense! Rakitin explained it all to me yesterday, brother, and it simply bowled me over. It's magnificent, Alyosha, this science! A new man's arising―that I understand... And yet I am sorry to lose God!”

“IT IS SO CURIOUS how hearing something once in your youth can dictate a thought pattern all the way through your life. I was nine, a man said something nonchalantly, and now when I see a slate at age thirty-six, as far as I'm concerned, its primary use is for beheading boys. Once that's done it can be used for roofing.”

“For those who haven’t yet experienced climate collapse in our own bodies, a history not yet written into us, the feeling it arrives in the shape of shadows, an atmospheric wrongness, and harrowing predictions; these are stories that change our own. The moment we begin to truly engage with climate science, our narratives of self and future are whirled out of orbit.”

“You can never characterize anybody’s personality in detail. There should always be hidden and unknown aspects of any personality that can put you to confusion. However, you can nearly take it for guaranteed that if whoever is less talkative and sensitive, he/she is more aggressive and sadist by nature, because human brain is designed so that if cells in the communication and emotion centers there are killed off, the cells in the sex and aggression centers will grow. There is a proportion between these centers, which means that if one contains more neurons, the other does less. This negative personality trait can be hidden with the naked eye, but it exists in all probability.”

“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.”

“Thus the nerve may be taken to be a relay with essentially two states of activity: firing and repose. Leaving aside those neurons which accept their messages from free endings or sensory end organs, each neuron has its message fed into it by other neurons at points of contact known as synapses. For a given outgoing neuron, these vary in number from a very few to many hundred. It is the state of the incoming impulses at the various synapses, combined with the antecedent state of the outgoing neuron itself, which determines whether it will fire or not. If it is neither firing nor refractory, and the number of incoming synapses which “fire” within a certain very short fusion interval of time exceeds a certain threshold, then the neuron will fire after a known, fairly constant synaptic delay. This is perhaps an oversimplification of the picture: the “threshold” may not depend simply on the number of synapses but on their “weight” and their geometrical relations to one another with respect to the neuron into which they feed; and there is very convincing evidence that there exist synapses of a different nature, the so-called “inhibitory synapses,” which either completely prevent the firing of the outgoing neuron or at any rate raise its threshold with respect to stimulation at the ordinary synapses. What is pretty clear, however, is that some definite combinations of impulses on the incoming neurons having synaptic connections with a given neuron will cause it to fire, while others will not cause it to fire. This is not to say that there may not be other, non-neuronic influences, perhaps of a humoral nature, which produce slow, secular changes tending to vary that pattern of incoming impulses which is adequate for firing.”

“The neurons that rested in deep slumber for decades started to fire; now, they are incessant and unstoppable. The faintest spark has set in motion a raging wildfire in my brain taking me back to dreamy places.”

“Our brains contain one hundred billion nerve cells (neurons). Each neuron makes links with ten thousand other neurons to form an incredible three dimensional grid. This grid therefore contains a thousand trillion connections - that's 1,000,000,000,000,000 (a quadrillion). It's hard to imagine this, so let's visualise each connection as a disc that's 1mm thick. Stack up the quadrillion discs on top of each other and they will reach the sun (which is ninety-three million miles from the earth) and back, three times over.”

“I feel as though dispossessed from the semblances of some crystalline reality to which I’d grown accustomed, and to some degree, had engaged in as a participant, but to which I had, nevertheless, grown inexplicably irrelevant. But the elements of this phenomenon are now quickly dissolving from memory and being replaced by reverse-engineered Random Access actualizations of junk code/DNA consciousness, the retro-coded catalysts of rogue cellular activity. The steel meshing titters musically and in its song, I hear a forgotten tale of the Interstitial gaps that form pinpoint vortexes at which fibers (quanta, as it were) of Reason come to a standstill, like light on the edge of a Singularity. The gaps, along their ridges, seasonally infected by the incidental wildfires in the collective unconscious substrata. Heat flanks passageways down the Interstices. Wildfires cluster—spread down the base trunk Axon in a definitive roar: hitting branches, flaring out to Dendrites to give rise to this release of the very chemical seeds through which sentience is begotten. Float about the ether, gliding a gentle current, before skimming down, to a skip over the surface of a sea of deep black with glimmering waves. And then, come to a stop, still inanimate and naked before any trespass into the Field, with all its layers that serve to veil. Plunge downward into the trenches. Swim backwards, upstream, and down through these spiraling jets of bubbles. Plummet past the threshold to trace the living history of shadows back to their source virus. And acquire this sense that the viruses as a sample, all of the outlying populations withstanding: they have their own sense of self-importance, too. Their own religion. And they mine their hosts barren with the utilitarian wherewithal that can only be expected of beings with self-preservationist motives.”

“I hope to inspire you to recognize that your reason for existence is to pursue the things that excite you the most. The best thing you can do--for yourself and everyone else--is to act on the things you're most passionate about. When you do, you'll shine, and everyone else will see that brilliance. On a biological level, the mirror neutrons of the people around you will activate. They will recognize that they can also follow their dreams and accomplish things they have always wanted to accomplish. On a spiritual level, their souls will remember their reason for being.”

“Concepts of memory tend to reflect the technology of the times. Plato and Aristotle saw memories as thoughts inscribed on wax tablets that could be erased easily and used again. These days, we tend to think of memory as a camera or a video recorder, filming, storing, and recycling the vast troves of data we accumulate throughout our lives. In practice, though, every memory we retain depends upon a chain of chemical interactions that connect millions of neurons to one another. Those neurons never touch; instead, they communicate through tiny gaps, or synapses, that surround each of them. Every neuron has branching filaments, called dendrites, that receive chemical signals from other nerve cells and send the information across the synapse to the body of the next cell. The typical human brain has trillions of these connections. When we learn something, chemicals in the brain strengthen the synapses that connect neurons. Long-term memories, built from new proteins, change those synaptic networks constantly; inevitably, some grow weaker and others, as they absorb new information, grow more powerful.”

“Since the universe must contain millions of appropriate planets, consciousness in some form - but not with the paired eyes and limbs, and the brain built of neurons in the only example we know - may evolve frequently. But if only one origin of life in a million ever leads to consciousness, then Martian bacteria most emphatically do not imply Little Green Men.”

“In our constant search for meaning in this baffling and temporary existence, trapped as we are within our three pounds of neurons, it is sometimes hard to tell what is real. We often invent what isn't there. Or ignore what is. We try to impose order, both in our minds and in our conceptions of external reality. We try to connect. We try to find truth. We dream and we hope. And underneath all of these strivings, we are haunted by the suspicion that what we see and understand of the world is only a tiny piece of the whole.”

“The first attempts to consider the behavior of so-called "random neural nets" in a systematic way have led to a series of problems concerned with relations between the "structure" and the "function" of such nets. The "structure" of a random net is not a clearly defined topological manifold such as could be used to describe a circuit with explicitly given connections. In a random neural net, one does not speak of "this" neuron synapsing on "that" one, but rather in terms of tendencies and probabilities associated with points or regions in the net.”

“When the brain is working to remember something, similar patterns of neurons fire as they did during the perception of the original event. These networks are linked, and each time we revisit them, they become stronger and more associated. But they need the proper retrieval cues--words, smells, images-- for them to be brought back as memories”

“When you're designing and inventing the way I did, every minute of your life is put - every neuron in your brain into trying to think about the little code and how you can maybe have one less line of code and a little bit more straightforward from the beginning to the answer. And you don't have time to think about companies and products and how would I build this. So Steve Jobs and I were a very necessary pair.”
