Area 27 of Brodmann-1909 is a cytoarchitecturally defined cortical area that is a rostral part of the parahippocampal gyrus of the guenon (Brodmann-1909). It is commonly regarded as a synonym of presubiculum (Crosby-62).

The dorsal part of the presubiculum is more commonly known as the postsubiculum[1] and is of interest because it contains head direction cells, which are responsive to the facing direction of the head.[2]
