Luigi galvani: found that if an electrical current is applied to a dissected nerve, the muscle connected to the nerve contracts electrical stimulation passing an behaviour a muscular contraction. Gustave theodor fritsch & eduard hitzig: demonstrated that electrical electrical current from the uninsulated tip of an electrode onto a nerve to produce stimulation of the neocortex causes mvmnt. conscious person, producing mvmnt of the body. Roberts bartholow: first described the effects of human brain stimulation on a. Richard caton: first to measure the brain"s electrical currents w/ a sensitive voltmeter a device that measures the flow and strength of the electrical voltage by.
