This image displays a single human neuron (white) and all of the axons from other neurons that connect to it. The blue threads are inhibitory axons, while the green ones are excitatory axons. Neurons are the cellular building blocks of the nervous system.
The 3D image above shows excitatory neurons colored by their depth from the surface of the brain. Blue neurons are those closest to the surface, and fuchsia marks the innermost layer.
A rendering shows all of the excitatory (pyramidal) neurons in a part of the brain sample, at varying degrees of magnification and tilt. They are colored by size; the cell body (central core) of the cells ranges from 15 to 30 micrometers across.
