- The deep furrows are called fissures and shallow ones are called sulci (singluar; sulcus). The ridges between the sulci are known as a gyri (singular; gyrus). Major sulci and fissures divide each hemisphere into four lobes: the frontal, parietal, occipital, and temporal lobes.

These intricate folds are a hallmark feature of the human brain, contributing to its remarkable complexity and functional specialization. In this article, we delve into the anatomy of brain fissures, their developmental origins, and their significance in brain function and evolution.
Aug 19, 2021 · Cerebral sulci and fissures are grooves between the adjacent gyri on the surface of the cerebral hemispheres. By allowing the cortex to invaginate to form sulci and gyri the surface area of the cortex is increased threefold 4 .

Aug 10, 2023 · They are called fissures simply because they are a different shape of hole, they look more like a crack or cleft, and typically occur between separate anatomical structures. For example, the superior orbital fissure lies between the lesser and greater wings of the sphenoid bone.

A fissure or sulcus is a natural division, deep furrow, or a groove that separates the gyri of the brain. The main groove of the brain is the interhemispheric fissure which divides the brain into two halves.

Sep 28, 2022 · On its lateral and medial surfaces, the cerebral cortex is noticeably convoluted. This increases the surface area of the brain so more nerve cells (or neurons) can be present. The deep furrows are called fissures and shallow ones are called sulci (singluar; sulcus).
Gyrus (plural gyri) is a ridge on the cerebral cortex. Sulcus (plural sulci) is a groove that separates gyri. The cerebral hemispheres are separated by a median cleft: the inherhemispheric fissure (great longitudinal fissure).
