GENERAL HISTOLOGY

Detailed explanation-1: -The cerebrum is where the more complex brain functions occur and in humans and other large vertebrates, this structure has grown to form a convoluted layer of grey matter.

Detailed explanation-2: -The tissue called “gray matter” in the brain and spinal cord is also known as substantia grisea, and is made up of cell bodies. “White matter", or substantia alba, is composed of nerve fibers.

Detailed explanation-3: -The grey matter in the spinal cord consists of interneurons, as well as the cell bodies of projection neurons.

Detailed explanation-4: -Finally, perched above the brain stem and cerebellum, is the cerebral cortex. This is probably what you think of when you picture the brain-and it is responsible for sensory perception, information processing, and memory, learning, and decision-making.
