The term area 39 of Brodmann refers to a subdivision of the cytoarchitecturally defined parietal region of cerebral cortex in the human. It corresponds to the angular gyrus surrounding the caudal tip of the superior temporal sulcus. Dorsally it is bounded approximately by the intraparietal sulcus. Cytoarchitecturally it is bounded rostrally by the area 40 of Brodmann (human), dorsally and caudally by the area 19 of Brodmann (human), and ventrally by the area 37 of Brodmann (human) ( Brodmann-1909 ). Its equivalent in the nomenclature of Glasser-2016 is areas PG.
