Exploration of those parts of the brain supplied by the posterior cerebral artery
Tapetum and tail of caudate nucleus
The ependymal lining has been removed to expose the tapetum (10), a broad band of fibers sweeping downward from the corpus callosum over the inferior horn of the ventricle into the temporal lobe. As the tail of the caudate nucleus (13) passes down from the floor of the central part of the ventricle into the roof of the inferior horn it parallels the anterior edge of the tapetum (left border as seen in the view). Only a fragmentary part of the tail of the caudate nucleus could be satisfactorily demonstrated in this specimen.
