Animation of pyramidal neurons passing signals to each other. Pyramidal neurons are found in the cerebral cortex of the brain, as well as in the corticospinal tract and in parts of limbic system including the hippocampus and amygdala. They are named for their distinctly-shaped cell bodies (white), which have many inward connections (dendrites) at the wide end, and one outward axon emerging from the narrow end. All these processes are highly branched, forming a complex network. Depending on their location, they are involved in motor control, sensory processing and higher cognitive functions.
