Exploration of the brain from its basal aspect

Contents of lateral fissure exposed by partial resection of temporal lobe

The temporal lobe has been further cut away to expose the insula, the frontal operculum and branches of the middle cerebral artery lying in the lateral fissure. The arachnoid membrane and pia mater which covered a part of the resected temporal lobe are left in situ. The hypophysis has been removed.
