Exploration of the brain from its basal aspect
Anterior limb of internal capsule, anterior commissure and parolfactory area
The head of the caudate nucleus has been scraped away to reveal more clearly the fibers of the anterior limb of the internal capsule. These pass forward in discret bundles through the confluent parts of the caudate nucleus and putamen, the whole being named the "corpus striatum." Relations of the anterior commissure, anterior perforated substance and parolfactory area (now partly exposed by dissection) may also be seen.
