Exploration of the brain from the medial aspect
Radiation of corpus callosum
The radiation of the corpus callosum has been made visible by the removal of tissue from the medial surface of the hemisphere including the cingulum, gyrus cinguli, paracentral lobule, and parts of the superior frontal gyrus and superior parietal lobule. The parieto-occipital fissure bounds the dissected area posteriorly. In the dissection there is a complex interlacing of the radiations of the corpus callosum and internal capsule together with the fibers of numerous association systems. This makes it impossible to display the course of most of the fiber bundles comprising the corona radiata.
