PSYA01H3 Chapter Notes - Chapter 3: Occipital Lobe, Parietal Lobe, Corpus Callosum
Document Summary
Responsible for most complex aspects of perception, emotion, movement and thought. Sits over the rest of the brain, like a mushroom cap shielding the underside and stem and it is the wrinkled surface you see when looking at the brain with the naked eye. Gyri (gyrus) the smooth surfaces of the cortex the raised part. Sulci and gyri represent a triumph of evolution. The cerebral cortex occupies roughly the area of a newspaper page. Fitting that much cortex into a human skull is a tough task. The cortex, with its wrinkles and folds, holds a lot of brainpower in a relatively small package that fits comfortably inside the human skull. Functions of the cerebral cortex can be understood at 3 levels: the separation of the cortex into 2 hemispheres. The 2 hemispheres are more or less symmetrical in their appearance and, to some extent, in their functions.
