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.
English: Fusiform gyrus with all major sulci delimiting it, displayed on a 3D-printed brain of a healthy adult. As we view the brain from below, the right hemisphere is on the left side of the image; red – fusiform gyrus; yellow – occipitotemporal sulcus (OTS); green – collateral sulcus (CoS); blue – mid-fusiform sulcus (MFS).
Gyrification in the human brain. Gyrification is the process of forming the characteristic folds of the cerebral cortex. [1] The peak of such a fold is called a gyrus (pl. gyri), and its trough is called a sulcus (pl. sulci).
In neuroanatomy, a gyrus (pl.: gyri) is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci (depressions or furrows; sg. : sulcus ). [ 1 ] Gyri and sulci create the folded appearance of the brain in humans and other mammals .
Diagram of gyri of brain viewed on lateral hemisphere. Occipital gyri shown lower right. The border between the occipital lobe and the parietal and temporal lobes is characterized by different gyri: the superior occipital gyrus (also known as gyrus occipitalis superior), middle occipital gyrus (or gyrus occipitalis medius), inferior occipital gyrus (or gyrus occipitalis inferior), and ...
The postcentral sulcus of the parietal lobe lies parallel to, and behind, the central sulcus in the human brain. (A sulcus is one of the prominent grooves on the surface of the brain .) The postcentral sulcus divides the postcentral gyrus from the remainder of the parietal lobe .
The precentral sulcus is a part of the human brain that lies parallel to, and in front of, the central sulcus. [1] [2] A sulcus is one of the prominent grooves on the surface of the human brain. The precentral sulcus divides the inferior, middle and superior frontal gyri from the precentral gyrus.
