According to biologists, neocortex is a thin layer structure found in the cerebral cortex area of the brain. The neocortex is also responsible for human senses, the ability to speak and coordinate movement such as walking and lifting.
Neurons within the neocortex are arranged vertically within neocortical columns. In the human brain, the neocortex has 500,000 of these particular columns and each column is in turn comprised of 60,000 neurons.
