Document Summary
Biological psychology is the branch of psychology that studies the biological foundations of behavior, emotions, and mental processes. Relationship between biology and behavior is circular. Archeological evidence of brain surgery suggests that many years ago people tried to cure others by drilling holes in the skull (trephining or trepanation) with the hope to release demons or relieve feelings of pressure. Edwin smith surgical papyrus is the egyptian text which is the oldest known medical writing in history: the egyptians didn"t think the brain is important so they would remove it through the nostrils during mummification. Galen believed that the ventricles played an important role in transmitting messages to and from the brain: fluids flowing within the ventricles were believed to be continuous with fluids in the nerves. Reservoirs in the muscles would fill with these spirits causing the foot to pull away from the fire.
