Exploration of the brain from its basal aspect
Corpus callosum
The radiating fibers of the corpus callosum have been exposed by removal of the ependymal lining of the roof of the lateral ventricle. The junction of callosal fibers with those of the internal capsule (4) to form the corona radiata is seen from below.
