middle temporal gyrus

middle temporal gyrus (MTG)

The term middle 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 separated dorsally from the superior temporal gyrus by the superior temporal sulcus. Its boundary with the inferior parietal lobule is marked by an ill-defined line from the terminal descending limb of the lateral fissure to the equally ill-defined boundary between the temporal lobe and the occipital lobe. Its lower boundary with the inferior temporal gyrus is marked by the inferior temporal sulcus. It extends rostrally to the inferior margin of the hemisphere where its border with the inferior temporal gyrus is unmarked by anatomical feature. The middle temporal gyrus of the macaque is similar, except that the caudal boundary, while no more clearly defined than in the human, is with the angular gyrus of the inferior parietal lobule rather than with the occipital lobe. And its boundary with the inferior temporal gyrus is marked by three short sulci, which are topologically equivalent to the inferior temporal sulcus of the human, but, in the macaque, are named posterior middle temporal sulcus ( Martin-1996 ) middle temporal sulcus ( Krieg-1975 ), and anterior middle temporal sulcus ( Cheng-1997 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

Also known as: middle temporal gyrus, Gyrus temporalis medius, intermediate temporal gyrus, inferior temporal gyrus (Seltzer)

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.
