Quotes About Cortex

With me, something different and deep, in bright focus and pointing the way, arrived in the practice of hitchhiking. I am the spirit and the heart of hitchhiking, I am its cortex and its medulla, I am its foundation and its culmination, I am the jewel in its lotus.

My cerebral cortex, the gray matter that MIT neuroscientist Steven Pinker likens to 'a large sheet of two-dimensional tissue that has been wadded up to fit inside the spherical skull,' is riddled instead of whole.

Beauty has undergone a similar process, thanks to advertisers. Evolution gave us a circuit that responds to good looks—call it the pleasure receptor for our visual cortex—and in our natural environment, it was useful to have. But take a person with one-in-a-million skin and bone structure, add professional makeup and retouching, and you're no longer looking at beauty in its natural form. You've got pharmaceutical-grade beauty, the cocaine of good looks.

For the first time in longer than I can remember, I feel peaceful. Not happy. Not sad. Not anxious. Not horny. Just all the higher parts of my brain closing up shop. The cerebral cortex. The cerebellum. That's where my problem is. I'm now simplifying myself. Somewhere balanced in the perfect middle between happiness and sadness. Because sponges never have a bad day.

Our brain processes incoming sensory input from the bottom up, and if someone has a life with chaotic, uncontrollable, or extreme and prolonged stress, particularly early in life, they're more likely to act before thinking. Their cortex is not as active, and reactivity in the lower areas of the brain becomes more dominant.

Recent scientific research has reinforced the findings of people like Otnow and Athens by demonstrating that a traumatic upbringing can actually alter the anatomy of a person's brain. Brain scans performed on severely abused children have found that specific areas of the cortex—related not just to the intelligence but to the emotions—never develop properly, leaving them incapable of feeling empathy for other human beings.

My beats travel like a vortex, Through your spine, to the top of your cerebrum cortex

the cortex uses the same computational tool to accomplish everything it does.

There are neurons in the old part of our brain that are known to learn maps of the places we have visited, and these neurons have been under evolutionary pressure for so long that they are fine-tuned to do what they do. In mammals, the old brain parts where these map-creating neurons exist are called the hippocampus and the entorhinal cortex.

Training in rapid acoustic discrimination can apparently induce the left prefrontal cortex, which is normally attuned to fast-changing acoustic stimuli but is disrupted in dyslexics, to do its job. The region, even in adults, remains plastic enough...to develop such differential sensitivity after intensive training, the scientists concluded.

As you experience a growth of your cortex area. You'll have many new and exciting concepts occur to you, especially of a religious nature.

One implication of the limbic area is that it is an interface between the more impulsive and "primitive" brainstem and the higher, often more rational cortex. Integration in the brain would therefore honor the differences in these regions and promote their linkage* through collaboration, not internal warfare. An interpersonal neurobiology* approach enables the activity stemming from these regions to be known and then linked with other areas.

All day you have been on my mind, a steam iron pressing the convolutions from my cortex, ironing me flat. Worrying cooks my cells feverish. I am irritable with love boiling into anxiety, till I grow furious with you, lying under the surgeon's knife.

Los hipocampos, al igual que los núcleos del septo y la corteza orbitofrontal, tienen la capacidad de modular los núcleos amigdalinos.

An insight is a fleeting glimpse of the brain's huge store58 of unknown knowledge. The cortex is sharing one of its secrets. —Jonah Lehrer

The medium is the messenger to the cortex, and it begins to shape it from the very start.

What exactly is the role of the cerebral cortex in producing consciousness? The cortex expands the number of ways in which we can experience the world, which allows for a vast variety of possible conscious experiences and responses.

We detect mistakes with our orbital frontal cortex, part of the frontal lobe, on the underside of the brain, just behind our eyes. Scans show that the more obsessive a person is, the more activated the orbital frontal cortex is.

There are very fast-acting pathways in your brain that, with the first flush of threat, bypass your frontal cortex and rational thinking.12
