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.
Based on the differences in lamination the cerebral cortex can be classified into two parts, the large area of neocortex and the much smaller area of allocortex: The neocortex (also known as the isocortex or neopallium) is the part of the mature cerebral cortex with six distinct layers.
