Cerebral canals are a type of anatomical structure found in the brain. They are also known as cerebral sulci and are grooves or furrows that separate the gyri, or ridges, of the brain. ITERS is an acronym for the four main cerebral canals: the inferior temporal, the entorhinal, the retrosplenial, and the subicular. These canals are important for the functioning of the brain, as they provide pathways for the flow of cerebrospinal fluid and allow for communication between different parts of the brain.
