Brain and nerve synapse. Illustration of a human brain in an abstract jigsaw form, overlaid with a depiction of the junction between two nerve cells. The junction between a nerve cell and another cell is called a synapse. This is where chemicals known as neurotransmitters (red spheres) cross the gap from an axon (nerve cell extension) to trigger the other (postsynaptic) cell. The incoming nerve impulse (from top) releases the neurotransmitter, which crosses the gap and binds to receptors (holes) on the receiving nerve cell. Neurons (nerve cells) are seen in the background. The brain's computing and memory power arises from the billions of such connections between its nerve cells. | |
