The fornix is present, small but distinctive, just ventral to the corpus callosum. The internal capsule is gone. The pons, present most ventrally in the section, contains many dense bundles of cortical axons that have come via the cerebral peduncles. A large subset of these synapse here, others continue into the medulla. Dorsolateral cortex at this level is primary somatosensory cortex of the parietal lobe.
Ventrolateral cortex is primary auditory cortex of the temporal lobe.
Distinctive olfactory cortex is still present ventromedially. The hippocampus and the corpus callosum are gone. Optic radiations are dense fiber pathways coursing adjacent to the lateral ventricles that arise in the lateral geniculate nucleus and terminate in primary visual cortex. The section grazes, on the left, the caudal pole of the lateral geniculate nucleus and you can see how the optic radiations arise. The section grazes rostral cerebellum, very distinctive in appearance and present to either side of the brainstem.
