Quotes About Cortex

In the early Sixties, having begun to describe the physiology of cells in the adult cat visual cortex, David Hubel and I decided to investigate how the highly specific response properties of cortical cells emerged during postnatal development.

In 1983, I became the Vincent and Brook Astor Professor at The Rockefeller University, where I established a new Laboratory of Neurobiology and continued my close collaboration with Charles Gilbert on the circuitry of primary visual cortex.

Sich daran zu erinnern, wo das Erinnerungsvermögen liegt, das kann einem auch nur in einem cerebralen Cortex passieren.

This is the outer surface of the brain where much of our thinking is done. Unfolded, this surface layer would cover the area of a football field

Richard stood transfixed for a moment or two, wiped his forehead again, and gently replaced the phone as if it were an injured hamster. His brain began to buzz gently and suck its thumb. Lots of little synapses deep inside his cerebral cortex all joined hands and started dancing around and singing nursery rhymes.

Well, that was a huge step. We had an instruction set. We could move data around. We could do conditionals. We could do most of the things a simple chip can do. We had the visual cortex for our display. The auditory cortex for our speakers. The motor cortex for our input. On top of that, we could write any damn software we wanted.

our primate ancestors was the development of a larger cerebral cortex as well as the development of increased volume of gray-matter tissue in certain regions of the brain.32 This change occurred, however, on the very slow timescale of biological evolution and still involves an inherent

We have fifty billion neurons in the cerebellum that deal with skill formation, billions in the cortex that perform the transformations for perception and rational planning, but only about eighty thousand spindle cells dealing with high-level emotions.

Along with our many human propensities, we evolved a huge cerebral cortex with which we make decisions.

You stimulate the neo-cortex, it produces a symphony. But it's not just a symphony of perception. It's a symphony of your universe. Your reality.

Grace was pouring out everywhere, from hidden sounds, into Els's damaged auditory cortex. And all that secret, worldwide composition said the same thing: listen closer, listen smaller, listen lighter, to any noise at all, and hear what the world will still sound like, long after your concert ends.

mindfulness meditation will transform your reactivity to the signals by turning down the volume on your amygdala and orbital frontal cortex. But if you have trouble discriminating internal bodily cues, mindfulness meditation can amplify them by increasing the gain on the insula.

Hypnosis, whatever positive suggestions it may implant in the cortex to transduce into neurochemical immunological boosts, also begins with telling the patient to close her or his eyes and become more relaxed. Both closing the eyes and relaxing move the patient from beta waves/outer attention/sympathetic system to alpha-theta waves/inner attention/parasympathetic system.

This fifth circuit is bonded into the right cortex and neurologically linked to the limbic (first circuit) system and the genitalia. These neural links explain the sexual metaphor of "kundalini" or "serpent" energy used to describe this circuit in systems as varied as Indian Tantra, Gnosticism and Voodoo, and the Chinese yin yang (male-female) energies associated with it.

but then he remembered that the cortex inhibits the lower centers of the brain, so that low cortical arousal allows the more uninhibited behavior of the extrovert, while high cortical arousal is inhibitory and leads to introversion. This explained why drinking alcohol, a depressant which lowers cortical arousal, could lead to more excited and uninhibited behavior.

Si le cerveau des mammifères a évolué selon une certaine voie, celui des oiseaux en a suivi une autre . Progression dynamique plutôt que stagnation reptilienne. Au lieu de se déployer à la surface en gros plis grumeleux comme chez les mammifères, leur intelligence est enfouie dans le cortex. Comment voler avec une grosse tête ? Leur cerveau est compact, renferme plus de neurones dans un petit espace que tout autre animal.

the cerebral cortex that has grown enormously over the last few millennia, overshadowing the ancient, instinctive lower brain.

Learning a new skill can change hundreds of millions of cortical connections.

The two diseases also seem to share a neural component. The symptoms of Tourette's apparently arise from impaired inhibition in the circuit linking the cortex and the basal ganglia-a circuit that is also impaired in OCD. The basal ganglia, you'll recall from Chapter 2, play a central role in switching from one behavior to another. Impairment there could account for the perseveration of obsessions and compulsions, as well as the tics characteristic of Tourette's.

You recently read me a quote by Faulkner: "The past isn't dead, it's not even past." So much of our adult lives is influenced by what happened to us as children. It is all still there, the memories, the feelings, and fears, stored just beneath the surface in the hidden crannies of our cortex.

If you (or any other mammal) bite into rancid food, the insular cortex lights up, causing you to spit it out, gag, feel nauseated, make a revolted facial expression—the insular cortex processes gustatory disgust. Ditto for disgusting smells.

Perhaps fifty years since we learned that reading problems of a type that we now call dyslexia aren't due to laziness but instead involve microscopic cortical malformations.

The sensory cortex and visual cortex are far away from each other. How do those tactile neurons "know" (a) that there's vacant property in the visual cortex; (b) that hooking up with those unoccupied neurons helps turn fingertip information into "reading"; and (c) how to send axonal projections to this new cortical continent? All are matters of ongoing research.

Furthermore, as shown with neuroimaging, when contemplating mouthwash versus soap, those who had just spoken a lie activated parts of the sensorimotor cortex related to the mouth (i.e., the subjects were more aware of their mouths at the time); those who had written the lie activated the cortical regions mapping onto their hand.
