Exploration of those parts of the brain supplied by the posterior cerebral artery

Optic tract and lateral geniculate body

The posterior cerebral artery has been retracted toward the left. The lateral geniculate body has been cut horizontally and its inferior part, together with the optic tract, pulled slightly out of position. The cerebral peduncle is seen as it ascends to form part of the internal capsule.
