Neuroanatomy is the study of the anatomy and organization of the nervous system. It includes the central nervous system (CNS), which consists of the brain and spinal cord, and the peripheral nervous system (PNS), which consists of the nerves and ganglia outside of the CNS that connect it to the rest of the body.
The nervous system is a complex network of nerves and cells that carry messages to and from the brain to the rest of the body. It has two main parts: the central nervous system (CNS), made up of the spinal cord and the brain, and the peripheral nervous system (PNS), the nerves and other types of supporting cells that branch throughout the rest of the body and communicate back to the CNS.
Some popular books suggest that the two sides of the brain are important to specific functions—that is, the right side of the brain is responsible for creativity while the left side handles your more analytical-type processing (sometimes referred to as “lateralization”). However, activity for most cognitive tasks is seen on both hemispheres.
The cerebral hemispheres are further subdivided into four major lobes: the occipital, towards the back of the brain; the parietal, just above the ear; the temporal, just behind the forehead temples; and the frontal, resting above the eyes at the very front of the cortex.
The parietal lobe is the home of the somatosensory cortex, the area of the brain responsible for processing sensation and touch information, as well as some aspects of spatial processing. For example, the lateral sulcus, the inner fold that separates the temporal lobe from the frontal lobe, and its neighbor, the temporal gyrus, house the primary auditory cortex, the area of the brain that processes sound information.
