Exploration of a brain cut in frontal section at the splenium of the corpus callosum
Anterior medullary velum, trochlear nerve, inferior and superior colliculi and pineal body
Branches of the superior cerebellar arteries have been cut away and only their main trunks have been left in the area of dissection. The great cerebral vein was removed to reveal its tributary internal cerebral veins and the underlying pineal body. The corpora quadrigemina are well exposed.
