Talk about gray matter

In the brain, the gray matter is located in the outer region of the cerebral hemispheres (cerebral cortex) and in the very central part (central gray nuclei). It is also found on the surface of the cerebellum (cerebellar cortex), in the center of the brainstem (central nuclei) and in the inner part of the spinal cord. The gray matter is characterized by its richness in blood capillaries, and by the presence of the cell bodies of neurons, their dendrites and the initial part of their axon as well as the terminal part of the axons derived from neighboring or distant cell bodies (some axons remain naked in the gray matter). It is therefore in the gray matter that the interneuronal connections (synapses) are established. Astrocytes are more numerous than oligodendrocytes in the gray matter.
