A gyrus is a ridge-like elevation found on the surface of the cerebral cortex. This region perceives various somatic sensations from the body, including touch, pressure 2.It is also called the somatosensory cortex, because the neurons in the postcentral gyrus receive information from sensory receptors in the body, including skin, muscles and joints. This gyrus works by creating and organizing a map of the body, known as the homunculus or ‘little man. It represents the Brodmann area 39. It surrounds a gyrus (pl. The parahippocampal gyrus (or hippocampal gyrus [1]) is a grey matter cortical region of the brain that surrounds the hippocampus and is part of the limbic system. Each ridge is surrounded by fissures known as sulci (singular: sulcus). The limbic system is a complex set of brain structures involved in emotion, motivation, memory, and behavior regulation. Each lobe has its own gyri and sulci that correspond to different functions and regions of the brain. The inferior or orbital surface of the frontal lobe is concave, and rests on the orbital plate of the frontal bone. (Connecting Healthcare Teams with Visual Insight) Digital Dictation Equipment.
