The cortex is the part covering certain organs. The cerebral cortex is an organic tissue, also called gray matter, covering the two hemispheres of the brain and is a few millimeters thick. The cerebral cortex is composed of different layers, more or less numerous depending on the region of the covered hemisphere. The cerebral cortex is in charge of what is called the "elaborate nerve function" and is grouped into areas with different functions including sensory, motor, and association. The cerebral cortex is involved in many cognitive functions including among others, some meaning, language, voluntary actions of motor skills and memory.
