The Grey Matter

Grey matter is a key part of the brain and spinal cord composed mainly of nerve cell bodies, dendrites, and supporting cells. It is responsible for processing information, enabling functions like sensory perception, muscle control, decision-making, and memory. Think of it as the brain’s information hub, where incoming signals are interpreted and responses are coordinated. Grey matter is found in regions such as the cerebral cortex, which handles higher-level thinking, and deep structures that regulate emotions and other vital processes. Its health and density are crucial for cognitive function and overall neurological well-being.
