Exploration of the brain from its basal aspect
Lamina terminalis
The rostral lamina (8) of the corpus callosum has been cut back to the midline and medial parts of the hemisphere removed to expose the lamina terminalis (9). The lamina terminalis is easily separated from the callosal fibers and it can be seen to extend anteriorly within the septum pellucidum. The longitudinal fibers seen in the previous stage can also be followed forward. The column of the fornix is removed.
