Gray matter forms a surface layer over the cerebrum and cerebellum. It also is located in deeper masses called nuclei. Gray matter is composed of neurosomas, dendrites, and synapses.
White matter is deep to the gray matter in most of the brain. It also surrounds the gray matter nuclei. White matter is composed of tracts of axons.
