superior temporal gyrus (STG)

The term superior temporal gyrus refers to one of six convolutions of the temporal lobe identified by dissection in the human ( Carpenter-1983 )...four in the macaque ( Martin-2000 ). Located on the lateral aspect of the cerebral hemisphere, it is the most dorsal of the temporal gyri. It is separated from the frontal lobe by the lateral fissure. Two short oblique convolutions appear on its upper surface (which forms the lower bank of the lateral fissure): the anterior transverse temporal gyrus and the posterior transverse temporal gyrus. Its boundary with the inferior parietal lobule is marked by the terminal descending limb of the lateral fissure with an ill-defined extension to the superior temporal sulcus. The latter marks its lower boundary with the middle temporal gyrus. It extends rostrally to the temporal pole where its border with the inferior temporal gyrus is unmarked by anatomical feature. Deep in the lateral fissure it is separated from the insula by the inferior limiting sulcus. The superior temporal gyrus of the macaque is similar, except that no transverse temporal gyrus appears on its dorsal surface; the lateral fissure separates it from the supramarginal gyrus of the inferior parietal lobule as well as from the frontal lobe; and it wraps around the temporal pole a short distance to the rhinal sulcus, which separates it from the limbic lobe ( Martin-2000 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

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.
