Exploration of the brain from its lateral aspect
Lentiform nucleus, uncinate fasciculus and inferior occipitofrontal fasciculus
The medullary center of the insula and the immediately underlying thin gray lamina of the claustrum have been taken away and most of the fibers of the external capsule removed to expose the lateral surface of the lentiform nucleus. A few vertically coursing fibers of the external capsule remain on the lentiform nucleus. Removal of the insular tissue also reveals the internal capsule (2) as it emerges above the putamen.
