Exploration of the brain from its basal aspect
Transverse fissure and lateral ventricle exposed by removal of thalamus
The thalamus has now been cut away so that only its most medial and anterior portions remain. The lamina affixa (6), which covered the upper lateral part of the thalamus, is partially removed so that in effect the choroidal fissure (8) is opened from below and one looks directly into the medial part of the body of the lateral ventricle which is collapsed. The roof of the ventricle, formed by the corpus callosum, is seen at (7).

2 . Ependymal membrane of superior surface of caudate nucleus
3 . Superior occipitofrontal fasciculus
4 . Internal capsule (cut across at junction with corona radiata)
5 . Superior longitudinal fasciculus
6 . Lamina affixa (partially cut away)
7 . Corpus callosum (inferior surface visible through body of lateral ventricle)
