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

Occipital radiation of corpus callosum; pulvinar

Removal of a portion of the cingulum (15) has exposed the right pulvinar of the thalamus (17) and, just above it, the occipital radiation of the corpus callosum (16), the two separated by the transverse fissure. Note the spiralling course of the fibers in the radiation.
