What is "grey matter"?
Grey matter refers to the tissue in the central nervous system that predominantly contains cell bodies of neurons. It forms the outer layer of the cerebral cortex and clusters within the deeper regions of the brain and spinal cord. Grey matter plays a crucial role in processing and integrating sensory information, motor control, memory, and cognition. Its distinctive grey appearance is due to the presence of neuronal cell bodies and their associated structures, highlighting its importance in neural communication and information processing within the body.
Examples

2. Our brains have two kinds of neural tissue: grey matter and white matter.
3. Dolphins also have more grey matter than humans, and their grey matter has more folds in it than humans' grey matter.
4. The grey matter processes information in the brain, directing signals and sensory stimuli to nerve cells, while white matter is mostly made up of fatty tissue and nerve fibers.
