Gray matter


Gray matter is a tissue of the central nervous system of a grayish color. It is located in the encephalon and spinal cord, at the bottom and on the surface of the brain. It is a complex structure consisting of nerve cells and non-neural glia (interstitial tissue that protects cells). The gray matter plays a role in receiving messages, reviewing the information, and preparing responses. Some diseases (such as Alzheimer's disease) are caused by lesions in the gray matter of the cortex.
