Exploration of the brain from its basal aspect

Close-up view of arteries entering anterior perforated substance

The hypophysis and optic chiasm are retracted toward the pons. The right posterior communicating artery (17) is divided and the internal carotid artery displaced forward to demonstrate the recurrent branch of the anterior cerebral artery (artery of Heubner) and the perforating branches of the anterior choroidal artery.
