superior temporal sulcus

superior temporal sulcus (sts)

The term superior temporal sulcus refers to a prominent sulcus that lies parallel to the lateral fissure in the temporal lobe of the human ( Carpenter-1983 ) and the macaque ( Martin-2000 ). Identified by dissection, it marks the boundary between the superior temporal gyrus above and the middle temporal gyrus below. In the human it extends into the angular gyrus of the parietal lobe ( Duvernoy-1992 ). In the macaque it marks the boundary between the angular gyrus and the supramarginal gyrus of the parietal lobe ( Martin-2000 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

Also known as: superior temporal sulcus, Sulcus temporalis superior, superior temporal fissure, parallel sulcus, Sulcus temporalis primus, sulcus t1

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
