Document Summary
Lecture 5: dancin", shakin", and locomotin": movement and the brain - reflexes. Descartes: motions that don"t depend on the mind. Heartbeat, digestion, nutrition, respiration when asleep: motions that do depend on the mind. These occur without the mind attending to them. Marie-jean-pierre flourens: cerebellum: removed cortex from pigeons. Birds wouldn"t fly/eat on their own, but swallowed food given to them and flew if tossed in the air. They did respond to sensory input, stimuli. But didn"t generate motion themselves: removed cerebellum slice by slice. Couldn"t control balance, didn"t know where their feet were: hypothesized that the cerebellum controlled motor coordination. In medieval times, it was considered to be the result of possession/witchcraft. Called st. vitus"s dance: streptococcal bacterium responsible for sydenham"s chorea.
