Nerve Impulse (image) Ohio State University Caption This image of a neuron illustrates the movement of a nerve impulse along an axon -- the long, slender extension of the nerve cell body. Ohio State University researchers have discovered how a key protein finds its way to the right spot on the axon to launch these vital electrical impulses, which enable communication of nerves' sensory, movement and memory signals to and from the brain.
