Exploration of the brain from the medial aspect
Claustrum, inferior occipitofrontal fasciculus, amygdaloid nucleus and inferior horn of lateral ventricle
The thin gray lamina of the claustrum has been exposed by removal of part of the external capsule. More posteriorly in this area the medial fibers of the inferior occipitofrontal fasciculus (11) are also uncovered. The choroidal fissure is opened and the substantia innominata and part of the amygdaloid nucleus removed so that the inferior horn of the lateral ventricle can be seen.
