Gray matter
Gray matter is a key component of the central nervous system, primarily found in the brain and spinal cord. It consists mostly of neuronal cell bodies, which are responsible for processing information. Gray matter is involved in various functions, including muscle control, sensory perception, memory, emotions, and decision-making. It contrasts with white matter, which contains myelinated axons that connect different brain regions. The amount and health of gray matter can influence cognitive abilities and overall brain function, making it essential for everyday activities and complex thinking.
