In the human brain, the superior temporal sulcus (STS) is the sulcus separating the superior temporal gyrus from the middle temporal gyrus in the temporal lobe of the brain.A sulcus (plural sulci) is a deep groove that curves into the largest part of the brain, the cerebrum, and a gyrus (plural gyri) is a ridge that curves outward of the cerebrum.
The superior temporal gyrus (STG [1]) is one of three (sometimes two) gyri in the temporal lobe of the human brain, which is located laterally to the head, situated somewhat above the external ear. The superior temporal gyrus is bounded by: the lateral sulcus above; the superior temporal sulcus (not always present or visible) below;
The brain contains four main lobes: temporal lobe, parietal lobe, frontal lobe, and the occipital lobe. The temporoparietal junction lies in the region between the temporal and parietal lobes, near the lateral sulcus (Sylvian fissure). Specifically, it is composed of the inferior parietal lobule and the caudal parts of the superior temporal ...
Superior sulcus of the human brain. Superior frontal sulcus, a sulcus between the superior frontal gyrus and the middle frontal gyrus . Superior temporal sulcus, the sulcus separating the superior temporal gyrus from the middle temporal gyrus in the temporal lobe; A groove in the first rib. It may be compressed in Pancoast tumors (also called ...
Axial sulcus develops in the long axis of a rapidly growing homogeneous area e.g. postcalcarine sulcus in the long axis of the striate area. Operculated sulcus separates by its lips into two areas and contains a third area in the walls of the sulcus e.g. lunate sulcus is an operculated sulcus, separating the striate and parastriate areas.
The cingulate cortex is a part of the "grand lobe limbique" of Broca (1878) that consisted of a superior cingulate part (supracallosal) and an inferior hippocampic part (infracallosal). [26] The limbic lobe was separated from the remainder of the cortex by Broca for two reasons: first because it is not convoluted, and second because the gyri ...
Middle temporal gyrus is a gyrus in the brain on the temporal lobe. It is located between the superior temporal gyrus and inferior temporal gyrus. It corresponds largely to Brodmann area 21. The middle temporal gyrus is bounded by: the superior temporal sulcus above; the inferior temporal sulcus below;
