Sulcus (neuroanatomy) - Wikipedia In neuroanatomy, a sulcus (Latin: "furrow"; pl : sulci) is a shallow depression or groove in the cerebral cortex One or more sulci surround a gyrus (pl gyri), a ridge on the surface of the cortex, creating the characteristic folded appearance of the brain in humans and most other mammals The larger sulci are also called fissures
Gyri and Sulci of the Brain - Simply Psychology Gyri (singular: gyrus) are the raised ridges or folds on the surface of the brain Sulci (singular: sulcus) are the grooves or furrows that separate the gyri This pattern of folds increases the brain’s surface area, packing in more neurons without increasing the brain’s size

Central sulcus: Anatomy, location and contents - Kenhub The central sulcus, also known as the sulcus of Rolando, is one of the largest sulci present in the brain It is located between the frontal and parietal lobes Apart from being the boundary between the two lobes, it demarcates the primary motor cortex ( precentral gyrus ) and primary somatosensory cortex ( postcentral gyrus )
Sulcus - Practical Psychology Sulcus is the patterned grooves or furrows on the brain’s cerebral cortex that increase the brain's size and separate the lobes and irregular-shaped ridges of the gyri Sulci are the folds between the brain’s lobes and the cell-carrying tissue that connects to the rest of the body
