The brain is dominated by two cerebral hemispheres. The cerebral cortex is the outermost layer of the cerebral hemispheres. Many terms refer to direction/location in the brain. Medial towards the middle and lateral towards the side. Ipsilateral same side (ex: sense of smell is ipsilateral) and contralateral opposite side (cross left side of the brain controls right side of the body, ex: auditory system) Anterior or rostral head end and posterior or caudal tail end. Proximal near the center and distal toward the periphery. Dorsal toward the back and ventral toward the belly, or front. To describe the flow of information (arrival and exit): Afferent carries information into a region of interest. Efferent carries information away from a region of interest.

The brain surface has two types of areas:
