Quotes About Brain regions

Studies of the brain have shown that the pattern of activity associated with an action changes as skill increases, with fewer brain regions involved. Talent has similar effects. Highly intelligent individuals need less effort to solve the same problems, as indicated by both pupil size and brain activity. A

in both birds and humans, the brain regions used more extensively in waking hours sleep more deeply during subsequent sleep—another similarity born of convergent evolution.

But in reality the brain is about circuits, about the patterns of functional connectivity among regions. The growing myelination of the adolescent brain shows the importance of increased connectivity.

Stick recording electrodes into numerous species' amygdalaefn9 and see when neurons there have action potentials; this turns out to be when the animal is being aggressive.fn10 In a related approach, determine which brain regions consume extra oxygen or glucose, or synthesize certain activity-related proteins, during aggression—the amygdala tops the list.

For one thing, part of the process is not even neural; that is, it does not involve regular nervous firing along chains of neurons. The process is humoral: chemical signals traveling in the blood capillaries bathe certain regions of the nervous system that are devoid of blood-brain barrier and can thus inform those brain regions directly about aspects of the ongoing homeostatic state.17

For example, from nouns to verbs to aspects of grammar, we each store language in different areas, recruiting different regions for different components.

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.

Neuroscientists have a biological explanation for why those downward negative-thought spirals happen in the first place. MRIs have shown that every time people think angry thoughts or imagine worst-case scenarios, they send a surge of blood flowing into the brain regions associated with depression and anger—which refuels their depression and anger in a destructive feedback loop.

This split between verbal and performance scores is often seen in abused or traumatized children and can indicate that the developmental needs of certain brain regions, particularly those cortical areas involved in modulating the lower, more reactive regions have been not been met.

Las alteraciones producidas en las regiones del cerebro encargadas de mantener esta cadencia a menudo son la causa de depresiones y de otros trastornos psiquiátricos.

Scientists are beginning to pinpoint the brain regions that become active when one feels fusion with a "higher power," such as God.36 Perhaps this brain region is also involved in love.

Study after study has indeed found a primary role for the prefrontal cortex in freely performed volitional activity. "That aspect of free will which is concerned with the voluntary selection of one action rather than another critically depends upon the normal functioning of the dorsolateral prefrontal cortex and associated brain regions," Sean Spence and Chris Frith concluded in "The Volitional Brain.

The subjects were each placed in a functional MRI scanner and shown the same set of fourteen video clips (including a sentimental music video, a bit of slapstick comedy, a political debate), and the blood flow to various brain regions was individually measured as they viewed

The "chronic overactivity of those brain regions implicated in social thought" can, writes Mitchell,
