Exploration of the brain from its lateral aspect
Relation of internal capsule to caudate and lentiform nuclei
Most of the left cerebral hemisphere has been removed by cutting through the region of the basal ganglia. The lentiform nucleus appears on the cut surface nearly surrounded by fibers of the internal capsule, which includes its anterior limb (7), posterior limb (6), retrolenticular portion (20) and sublenticular part (21). The more anterior fibers appearing underneath the lentiform nucleus are associated with the inferior occipitofrontal fasciculus (9) and external capsule. Note that the internal capsule lies between the lentiform and caudate nuclei. The latter is seen here through much of its extent. The genu of the internal capsule is not apparent at the level of this section.
