Exploration of the brain from its superior aspect
Corpus callosum, medial and lateral longitudinal striae
The radiations of the corpus callosum to the right hemisphere have been exposed by the removal of the gyrus cinguli (except its anterior portion seen cut transversely), the cingulum, a portion of the superior frontal gyrus and the precuneus. On the surface of the corpus callosum near the midline are seen delicate longitudinal bands, the medial and lateral longitudinal striae. The line of fusion of the cortex of the gyrus cinguli to the thin gray lamina (induseum griseum) covering the corpus callosum is seen at the medial edge of the lateral longitudinal stria (13). The classic figures of the "forceps major" (paired occipital radiations of the corpus callosum) and the "forceps minor" (paired frontal radiations of the corpus callosum) can be visualized in this specimen.
