Question

Can you state why some areas of the
brain and spinal cord are grey and some
are white?​

Answer 1

Answer:

White matter is buried deep in the brain, while gray matter is mostly found on the brain's surface, or cortex. The spinal cord, which transmits nerve impulses to and from the rest of the body, has the opposite arrangement: gray matter at its core with insulating white matter on the outside.
