Quotes About Cortex

On an incredibly simplistic level, you can think of depression as occurring when your cortex thinks an abstract thought and manages to convince the rest of the brain that this is as real as a physical stressor.

Following a trauma at any age, there's a reduction in the number of neural pathways between the limbic system (pertaining to feelings) and the cortex system (managing thought and cognition). So after being traumatized, you're less aware of your feelings.

We have this thin layer of prefrontal cortex made just for us, sitting on top of this big animal brain. Getting this thin little layer to handle more is unrealistic." The prefrontal cortex doesn't control most of the decisions we make every day. We can't fundamentally get more out of that unique, thin layer of prefrontal cortex. "It's already overtaxed,

The limbic system explodes during puberty, but the prefrontal cortex keeps maturing for another 10 years.

Intense fatigue or illness may also weaken the control of the cortex. Hence we find tired or sick persons responding to threats with a greater degree of undifferentiated anxiety. In psychoanalytic terms, we would speak of this as regression.

To see the organism in nature, the nervous system in the organism, the brain in the nervous system, the cortex in the brain is the answer to the problems which haunt philosophy. And when thus seen they will be seen to be in, not as marbles are in a box but as events are in history, in a moving, growing never finished process.

The brain devotes more cortical real estate to functions that its owner uses more frequently and shrinks the space devoted to activities rarely performed. That's why the brains of violinists devote more space to the region that controls the digits of the fingering hand. In response to the actions and experiences of its owner, a brain forges stronger connections in circuits that underlie one behavior or thought and weakens the connections in others.

With the prefrontal cortex down-regulated, most impulse control mechanisms go offline too. For people who aren't used to this combination, the results can be expensive.

This in no way implies the existence of multiple executives, each with their own planning and decision-making capacities. Instead, it suggests that the various component executive functions are achieved by a set of interconnected circuits that are spread over several brain regions in the frontal cortex, and even other regions,

The Blue Brain project expects to have a full human-scale simulation of the cerebral cortex by 2018. I think that's a little optimistic, actually, but I do make the case that by 2029 we will have very detailed models and simulations of all the different brain regions.

Just sitting quietly, doing nothing at all, your brain churns through more information in thirty seconds than the Hubble Space Telescope has processed in thirty years. A morsel of cortex one cubic millimeter in size—about the size of a grain of sand—could hold two thousand terabytes of information, enough to store all the movies ever made, trailers included, or about 1.2 billion copies of this book.

Deep in my cortex, the year is divided into reading seasons. The period from mid-October to Christmas, for instance, is 'ghost story' time, while Jane Austen and P. G. Wodehouse pretty much own April and May.

Attentional amplification of sensory awareness in any sensory medium is achieved by top-down signals from prefrontal cortex that modulate activity of single neurons in sensory brain areas in the absence of any sensory stimulation and significantly increase baseline activity in the corresponding target region.

stimulation of the medial frontal cortex gives one the feeling of the urge to move

For example, all of us talk to ourselves silently. When we do, the left brain, which controls language, consults the prefrontal cortex. But in schizophrenics, we now know, the left brain activates without permission from the prefrontal cortex

the more threatened or stressed we are, the less access we have to the smart part of our brain, the cortex

What you are pointing out is how adaptive it is to dissociate in many situations. If a soldier in combat simply went down the arousal continuum-and got to the flee and then fight stages-he would jump up and get shot. In order to maintain access to parts of his cortex-to think and behave in the ways he was trained to keep him alive in combat-he needs to dissociate to a certain degree.

If the challenge is going to build resilience, it has to be moderate—just right. Finding the "just right" is a major issue with children who have had trauma. Remember, they frequently live in a persistent state of fear. And fear shuts down parts of the cortex—the thinking part of the brain. In a classroom, what may seem to be a moderate, developmentally appropriate challenge for many children may be an overwhelming demand on a child with a sensitized stress response

Yes. Unfortunately, our schools are typically not trauma-aware and tend to prohibit many of the regulatory activities we've mentioned: walking, rocking, fiddling with things while listening to a lesson, listening to music with your earbuds while doing homework. "Somatosensory regulation," such as the rhythmic activities we have discussed, actually opens up the cortex and makes the reasoning parts of the brain more accessible for learning.

As we've said before, the cortex is the most uniquely human part of our body, and, no surprise, it gives rise to the most uniquely human capabilities: speech, language, abstract thinking, reflecting on the past, planning for the future.

major part of our worldview are mediated by our cortex.

Then you and that mutt hijacked my thoughts and started dancing Gangnam Style on my cerebral cortex.

Despite his title, the Secretary of the Interior was a shallow man. He was given to surfaces, not depths; to cortex, not medulla; to the puff, not the cream. He didn't understand the interior of anything: not the interior of a tenor sax solo, a painting or a poem; not the interior of an atom, a planet, a spider or his wife's body; not the interior, least of all, of his own heart and head.
