Exploration of those parts of the brain supplied by the posterior cerebral artery
Cingulum and inferior longitudinal fasciculus (continued)
The gyrus cinguli has been partially removed to reveal the course of the cingulum above the corpus callosum. Cortex which lay deep in the collateral fissure has been scraped away and the fusiform gyrus partly removed. More of the inferior longitudinal fasciculus is thus exposed. The brain is now turned so that more of the basal surface is shown than previously.
