Exploration of those parts of the brain supplied by the posterior cerebral artery
Longitudinal bundle of fibers within hippocampus continuous with medial longitudinal stria
Further dissection of the upper parts of the dentate fascia and hippocampus has revealed a discret system of fibers (15) which can be traced through the fasciola cinerea beneath the splenium of the corpus callosum and upward toward the induseum griseum (supracallosal gyrus) where it apparently is continued as the medial longitudinal stria. No evidence of a lateral longitudinal stria could be found in this specimen. Near the splenium some of the tissue of the induseum griseum is scraped away to reveal the fibers of the corpus callosum.
