WebMay 3, 2011 · Neurons pass messages to each other using a special type of electrical signal. Some of these signals bring information to the brain from outside of your body, such as the things you see, hear, and smell. Other signals are instructions for your organs, glands and muscles. Neurons receive these signals from neighbor neurons through their dendrites. WebNeurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances.
