Smokers should be informed that cigarettes could hasten the thinning of the brain's cortex
, which could lead to cognitive deterioration.
These data suggest that the activation of the visceral insular cortex
by serotonin may be responsible for the production of the elusive sensation of nausea, which is so difficult to treat.

In the occipital cortex
and midbrain, there were smaller cells (reduced total protein/DNA ratio) and a corresponding increase in cell packing density (DNA concentration), features that are likely to reflect neuronal damage and "reactive gliosis," that is, replacement with smaller, glial cells (O'Callaghan 1988, 1993; Roy et al.
The answer, he suggests, might involve the diverse connections between the cortex
and other parts of the brain.
There's constant messaging between the cerebellum and parts of the cerebral cortex
, so you can adjust your actions when conditions change.

The most prominent cortical changes, especially in superior-IQ children, occurred in the prefrontal cortex
, an area already implicated in analytical thinking.
IN CHANGE: The cerebral cortex
is the largest part of your brain.
For example, Duncan reported that a sharp jab to the skin causes reactions in the cortex
, the highest level of the brain, which controls thought and perception, and also in lower regions that govern feelings, memories and motions.
BOSTON, March 25, 2015 /PRNewswire/ -- Cortex
The new Cortex
-A9 processors are compatible with other Cortex
family processors and the popular ARM MPCore technology, thereby inheriting a rich ecosystem of OS/RTOS, middleware and applications to lower the costs associated with adopting a new processor.
Two new studies raise the bar on estimates of the magnitude of changes in nerve connections in the brain's outer layer, or cortex
, during adulthood.
The cerebral cortex
is a thin layer, less than 1/3 of a centimeter, that forms the outermost part of the cerebrum.
