Preferred Label : Brodmann (1909) area 38;
Uberon definition : Brodmann area 38, also BA38 or temporopolar area 38 (H), is part of the temporal cortex
in the human brain. 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. Cytoarchitecturally it is bounded caudally
by the inferior temporal area 20, the middle temporal area 21, the superior temporal
area 22 and the ectorhinal area 36 (Brodmann-1909). Cytoarchitectonic and chemoarchitectonic
studies find that it contains at least seven subareas, one of which, TG, is unique
to humans. 'The functional significance of this area TG is not known, but it may bind
complex, highly processed perceptual inputs to visceral emotional responses.' This
area is among the earliest affected by Alzheimer's disease and the earliest involved
at the start of temporal lobe seizures. [;
