WebJul 25, 2024 · The medial surface of the occipital lobe has a characteristic calcarine sulcus (calcarine fissure). It extends from the parieto-occipital sulcus to the occipital pole. The upper and lower banks of calcarine sulcus house the primary visual cortex. Each primary visual cortex receives visual information from the contralateral half of the brain. The gyri are part of a system of folds and ridges that create a larger surface area for the human brain and other mammalian brains. Because the brain is confined to the skull, brain size is limited. Ridges and depressions create folds allowing a larger cortical surface area, and greater cognitive function, to exist in the confines of a smaller cranium. The human brain undergoes gyrification during fetal and neonatal development. In embryonic deve…
