Cerebral cortex
The Cerebral cortex is the extensive outer layer of gray matter of the cerebral hemispheres, largely responsible for higher brain functions, including sensation, voluntary muscle movement, thought, reasoning, and memory. The human brain's wrinkled texture results in substantially more cortex than is present in other brains of similar size.
Cerebral cortex is typically 1-4mm thick.
Laminar pattern
The standard areas of cortex (isocortex) is characterized as having six distinct layers. From outside inward:
- Molecular layer
- External granular layer
- External pyramidal layer
- Internal granular layer
- Internal pyramidal layer
- Fusiform layer
Classification
Based on the differencies in lamination the cerebral cortex can be classified into two major groups:
Auxilliary classes are:
Based on supposed developmental differencies the following classification also appears:
