Makes up the outer layer of the brain. Most recent evolution of the human brain. Where the thinking cognitive function takes place. No communication between two hemispheres as with corpuscallosum. Hemispheric specialization: each half of the brain has its own area of specialization, dominant (left hemisphere, the hemisphere controls the opposite side of the body, right hemisphere: music appreciation, art appreciation, sculpture, perception, fantasy.
