Wilder Graves Penfield
Mapped out the functional areas of the cerebral cortex
Penfield's early research focused on improving the treatment of focal epilepsy by gentle electrical stimulation. He mapped out new functional areas of the human cerebral cortex, and discovered that stimulating parts of the cortex could evoke vivid and specific memories including sounds and smells. Penfield was a founder of the Montreal Neurological Institute and he wrote many books on brain physiology.
