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 ...

Receptor in the skin detects a stimulus (the change in temperature). Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons ...

The interface itself had to solve the problem of picking up the extremely weak nerve impulses while simultaneously avoiding interference from mains hum and fluorescent lights. They go into detail ...

How does one nerve cell transmit the nerve impulse to another cell? Electron microscopy and other methods show that it does so by means of special extensions that deliver a squirt of transmitter ...

These subtle waves were not enough to activate the cell's major signaling potential (a nerve impulse), but enough to make the ...
