Document Summary

Lecture 8 movement neuroscience adam groh. History of m1 countering penfield: schiber and hibbard planted small electrodes into the m1 of awake- monkeys performing simple hand movements (low voltage). From this experiment, they collected information representing the localization of neurons for the hand in m1, as spheres. A pictorial representation of the neuronal activation over time was created in a rasterplot. Rows represent different movement, and ticks are the firing of the single neuron. Darker areas indicated specificity in movement/direction of response. When the electrodes attached to the monkey"s brain were attached to a prosthetic, it was able to control its movement, despite any physical connection. This study indicated that m1 was not simply the fcp to movement: grazzino applied electrical stimulation to m1 in an awake monkey with an increased duration. After stimulation, the monkey always put its hand to its mouth demonstrating feeding behavior.
