The Cerebral Cortex and Its Functions
... The human brain hemispheres are covered in its greater part by an external layer of gray color called cerebral cortex. A deep cut into the brain would show that this gray surface has a thickness varying from 1 to 4 mm. Its largest part is composed by nerve cells (neurons) which receive impulses from ...
