Trepanation: boring holes into brains (around 7000s years ago in order to cure problems) Conducted on live subjects and indicted signs of healing. Different structures serve different functions: hand used to manipulate objects, while feet are used for walking. Hippocrates believed that the brain was involved with sensation and intelligence. Aristotle bleived the heart was center of intellect and that the brain was a radiator for cooling blood that was overheated. Galen used dissections of sheep brains: found out that the cerebrum is soft, but cerebellum is hard, deduced that cerebrum received sensations while cerebellum commands muscles. Cerebrum involved in sensation and perception and a repository of memory. Ventricles contain fluid but at the time believed that sensations and movements initiated by movement of humors via nerves (believed to be hollow tubes like blood vessels) Views of the brain from the renaissance to the 19th century.
