Anterior perforated substance

The anterior perforated substance is a bilateral irregularly quadrilateral area in front of the optic tract and behind the olfactory trigone, from which it is separated by the fissure prima; medially and in front, it is continuous with the subcallosal gyrus; it is bounded laterally by the lateral stria of the olfactory tract and is continued into the uncus.[1]
