Exploration of the brain from its basal aspect

External capsule, lentiform nucleus and deeper course of striate arteries

The main trunk of the middle cerebral artery has been retracted far laterally, the medullary center of the insula removed and the claustrum scraped away. The external capsule has been partially removed, the remaining portion being turned laterally to expose the lentiform nucleus. The course of the lateral striate arteries into the lentiform nucleus is visible.
