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.
There are particularly large asymmetries in the frontal, temporal and occipital lobes, which increase in asymmetry in the antero-posterior direction beginning at the central region. Leftward asymmetry can be seen in the Heschl gyrus, parietal operculum , Silvian fissure, left cingulate gyrus, temporo-parietal region and planum temporale.
The planum temporale makes up the superior surface of the superior temporal gyrus to the parietal lobe. [4] The posterior extent of the planum temporale has been variably defined, which has led to disputes to estimates of size and degree of asymmetry. [4]
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 OFA comprises a network of brain regions including the fusiform face area (FFA) and posterior superior temporal sulcus (STS) which support facial processing. The identification of the OFA emerged from neuroimaging studies, particularly fMRI and PET , which revealed heightened neural activity in response to facial stimuli within this ...
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 ...
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 ...
BA39 encompasses the angular gyrus, lying near to the junction of temporal, occipital and parietal lobes. This area is also known as angular area 39 (H). It corresponds to the angular gyrus surrounding the caudal tip of the superior temporal sulcus. It is bounded dorsally approximately by the intraparietal sulcus.
