where is the white and gray matter located in the brain?
Gray matter serves as the message processing centers of the brain and is in charge of the brainâs conscious thought. While gray matter is located on the outside of the brain and the inside of the spinal cord, white matter follows the opposite pattern. It is located within the brain and outside of the spinal cord. In humans, distribution of white and gray matter varies between the sexes.
White matter is located at the base of the brain between the cerebellum and the brainstem. It is made of long nerve fibers called axons. The axons are insulated by myelin, sheaths of fat that give the region the white color for which it is named. The myelin helps speed up the transmission of signals along the axons.
