The posterior commissure marks the boundary between the mesencephalon and diencephalon. The pulvinar represents the caudal thalamus having nuclei with visual function. The base of the puvinar is marked by the ascending sensory pathways pain and tactile as they project onto the sensory thalamus Lateral is the optic tract entering the lateral geniculate body and emerging optic radiations that spread rostral into the temporal lobe to curve and project caudal to the visual cortex.
