Middle temporal gyrus is a gyrus in the brain on the temporal lobe. It is located between the superior temporal gyrus and inferior temporal gyrus. It corresponds largely to Brodmann area 21. The middle temporal gyrus is bounded by: the superior temporal sulcus above; the inferior temporal sulcus below;
Besides Wernicke's area, the left posterior superior temporal gyrus (pSTG), middle temporal gyrus (MTG), inferior temporal gyrus (ITG), supramarginal gyrus (SMG), and angular gyrus (AG) participate in language comprehension. Therefore, language comprehension is not located in a specific area.
The superior temporal gyrus is involved in auditory processing, including language, but also has been implicated as a critical structure in social cognition. [ 2 ] [ 3 ] Various parts of the STG might be referred to as anterior (aSTG), middle (mSTG), and posterior (pSTG).
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 ...
These secondary areas interconnect with further processing areas in the superior temporal gyrus, in the dorsal bank of the superior temporal sulcus, and in the frontal lobe. In humans, connections of these regions with the middle temporal gyrus are probably important for speech perception. The frontotemporal system underlying auditory ...
red:Brodmann area 41, green:Brodmann area 42, note 1: BA41 is bounded medially by Brodmann area 52 and laterally by BA42, note 2: pSTG is posterior part of the superior temporal gyrus In human brain anatomy, an operculum (Latin, meaning "little lid") ( pl. : opercula ), may refer to the frontal, temporal, or parietal operculum, which together ...
The inferior temporal gyrus is one of three gyri of the temporal lobe and is located below the middle temporal gyrus, connected behind with the inferior occipital gyrus; it also extends around the infero-lateral border on to the inferior surface of the temporal lobe, where it is limited by the inferior sulcus.
BA21 is a subdivision of the cytoarchitecturally defined temporal region of the cerebral cortex. BA21 is superior to BA20 and inferior to BA40 and BA41.It is bounded rostrally by the temporopolar area 38 (H), ventrally by the inferior temporal area 20, caudally by the occipitotemporal area 37 (H), and dorsally by the superior temporal area 22 (Brodmann-1909).
