ImageSurfer: Visualization of Dendritic Spines
... When a neuron fires, it sends an electrical impulse down a long arm-like structure called an axon. At the end of the axon the impulse sets off a chemical transfer. The chemicals diffuse across a gap to dendrites, on neighboring receiver neurons. These neurons then fire their own electrical impulses ...
