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;
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).
BA 38 is at the anterior end of the temporal lobe, known as the temporal pole. BA38 is a subdivision of the cytoarchitecturally defined temporal region of cerebral cortex . It is located primarily in the most rostral portions of the superior temporal gyrus and the middle temporal gyrus .
The subcallosal cingulate gyrus CG25 which consists of BA25 as well as parts of BA24 and BA32 has been implicated as playing an important role in major depression and has been the target of deep brain stimulation to treat the disorder. [6] One study found that BA25 is metabolically overactive in treatment-resistant depression. [7]
The Heschl's gyrus/transverse temporal gyrus includes Wernicke's area and functionality, it is heavily involved in emotion-sound, emotion-facial-expression, and sound-memory processes. The entorhinal cortex is the part of the 'hippocampus system' that aids and stores visual and auditory memories.
[1] [2] It is located bilaterally, roughly at the upper sides of the temporal lobes – in humans, curving down and onto the medial surface, on the superior temporal plane, within the lateral sulcus and comprising parts of the transverse temporal gyri, and the superior temporal gyrus, including the planum polare and planum temporale (roughly ...
The area includes gray matter along the central gyrus and its extension into the postcentral gyrus. Taste: The primary gustatory area consists of the anterior part of the insula and the frontal operculum. [2] [3] [4] Olfaction: The olfactory cortex is located in the uncus which is found along the ventral surface of the temporal lobe. Olfaction ...
Brodmann area 37, or BA37, is part of the temporal cortex in the human brain. It contains the fusiform gyrus which in turn contains the fusiform face area, an area important for the recognition of faces. This area is also known as occipitotemporal area 37 (H). It is a subdivision of the cytoarchitecturally defined temporal region of cerebral ...
