The superior temporal sulcus runs along the lateral temporal lobe, parallel to the lateral sulcus, separating the superior and middle temporal gyri. Its back end turns up into the parietal lobe, where the angular gyrus arches around it. The cortex in its banks is important for social perception.

Separates the superior and middle temporal gyri; its banks combine vision and hearing to interpret faces, voices and movement of others.
The banks of the superior temporal sulcus respond to biological motion, eye gaze, facial expression and voices, and altered function here has been linked to autism. Its posterior end is an important landmark for the angular gyrus and the language network. Lesions may impair understanding of others' actions and intentions.
Impaired reading of gaze, facial expression or body movement linked to dysfunction around the superior temporal sulcus.
Infarction near the posterior sulcus that may cause aphasia in the dominant hemisphere.
