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 .

2023年9月19日 · Sulci are grooves that surround each gyrus, with deeper grooves termed fissures. They increase the cerebral cortex’s surface area and create boundaries between brain lobes. Primary sulci form independently before birth, while secondary sulci develop afterward due to other factors.

A depression or a groove found on the surface of an organ or tissue, as on the surface of the brain separating adjacent convolutions. Large sulci that divide the brain into lobes as well as the two hemispheres are more often called fissures. Plural: sulci. See fissure. calcarine sulcus See calcarine fissure.

2024年9月30日 · Brain sulci, labeled meticulously by anatomists, are the grooves or furrows that crisscross the surface of the brain. They’re not just random dents or creases; each sulcus has a specific name, location, and function, working in harmony with its neighboring structures to orchestrate the symphony of human cognition.

In biological morphology and anatomy, a sulcus (pl.: sulci) is a furrow or fissure (Latin fissura, pl.: fissurae).

2024年9月30日 · Brain sulci, derived from the Latin word “sulcus” meaning furrow or groove, are the deep folds that characterize the surface of the cerebral cortex. They’re like the Grand Canyons of your cranium, carving out distinct regions and increasing the surface area of the brain.

2021年8月19日 · 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. The result is that the surface area of the human cortex is 2200 cm 2, only a third of which can be seen on the surface 4.

2019年10月9日 · Folding of the cerebral cortex creates gyri and sulci which separate brain regions and increase the brain's surface area and cognitive ability. Gyri and sulci form boundaries within and between the lobes of the brain and divide it into two hemispheres.

The meaning of SULCUS is furrow, groove; especially : a shallow furrow on the surface of the brain separating adjacent convolutions.

Solid regions show regions of cortex located on the surface of the brain, and hatched areas, cortex that is buried in sulci. The complex human cerebral cortex consists of many folds, and …
