Document Summary

A flow of electrons from a body that contains a higher charge (more electrons) to a body that contains a lower charge (fewer electrons) Location to which electrons flow; lower charge. An electrical charge measured in volts; the ability to do work through the use of stored potential electrical energy. A measure of a difference in electrical potent. Storage of the ability for that structure to have a change of electric bolt activity. Builds up current, difference in electrons is the electrical potential. Electrical current applied to a dissected nerve causes the muscle connected to the nerve to twitch; concluded that electricity flows along the nerve. Passing an electrical current from the tip of an electrode through brain tissue, resulting in changes in the electrical activity of the tissue. Electrical stimulation of the neocortex causes movement (arms and legs) Used electrical stimulation to map the neocortex in humans. A device that measures the difference in electrical potential between two bodies.
