Document Summary
Chapter 1 neuroscience past, present and future: the name neuroscience is pretty young (1970s) but the study of the brain began a long time ago. Prehistoric ancestors would drill holes into skull to help cure illnesses (possibly headaches, mental disorders, or to give evil spirits and escape route) Recovered writings show that early physicians recognized many of the symptoms of brain damage. Heart, not brain, was considered the center of emotions and memories. Cerebellum is hard and cerebrum is soft. Because of this he thought the cerebrum must receive sensations while the cerebellum commands muscles. Why: he recognized that in order to form memories, they must imprint on the brain and he figured this would happen in the softer cerebrum, while galen"s reasoning was off, his deductions were not. Important breakthrough in neuroanatomy: same pattern of gyri (bumps) and sulci/fissures (grooves) can be found on the surface of every individual"s brain. Enables the packaging of the cerebrum into lobes.
