Document Summary

His book cerebri anatome was very influential: mapped higher functions: located memory. Jean-cesar le gallois (18th-19th century) the respiratory center. Every time a portion of the brain or spinal cord is destroyed, a function is stopped. He wanted to know which section was responsible for what. Identification of separate sensory and motor nerve roots in the spinal cord. Bell discovered the motor roots first buy only published a pamphlet. Magendie discovered the sensory function of the posterior roots. This is showing us that the nervous system itself can be localized (some can do what others can"t) The law: the separation of the motor and sensory roots. Bell was unwilling to do vivisection: he couldn"t work on sensory functions. Bumps and depressions on skulls are thought to be indications of brain development. Specific regions on the brain connected to specific functions organs of the mind . Gall examined people with extreme qualities and collected skulls to determine the map.
