Document Summary
13. 2 each region of the brain has distinct structural and functional characteristcs. The cerebrum of the adult brain is divided into a pair of large cerebral hemispheres. Their surfaces are highly folded and covered by a 1. 5 to 4. 5 mm thick superficial layer of gray matter called the cerebral cortex. Functions include conscious thought, memory storage and processing, sensory processing, and regulating. Fissures are deep grooves that subdivide the cerebral hemispheres. Gyri are folds in the cerebral hemispheres that increase its surface area. Sulci are shallow depressions in the cerebral hemispheres that separate adjacent gyri. skeletal muscle contractions. The diencephalon is the structural and functional link between the cerebral hemispheres and the rest of the. The thalamus contains relay and processing centers for sensory information. The hypothalamus, or floor of the diencephalon, contains centers involved with emotions, autonomic function, and hormone production. The cerebellum, partially hidden by the cerebral hemispheres, is the second-largest structure in the brain.
