Exploration of a brain cut in frontal section at the splenium of the corpus callosum
Orientation view, cerebellum partly resected
The lobulus centralis of the cerebellum has been cut away, without, however, disturbing the numerous branches of the superior cerebellar arteries which passed over its surface or within its sulci. Each lateral ventricle is cut open at the junction of its body, inferior horn and posterior horn. Note the oblique plane of section of the brain stem, passing through the brachia conjunctiva superiorly and the olive inferiorly.
