(FRAME-INFO (STRING "Anterolateral View of Brainstem. Most of the frontal lobe cortex and white matter have been dissected away, leaving behind e.g., parts of the internal capsule, corpus callosum and putamen. Find the lateral fissure for orientation. Note the interpeduncular fossa \(part of the subarachnoid space\) between the cerebral peduncles. The  oculomotor nerve \(III\) exits the brainstem in this fossa, but is not seen here. Focus on the cerebellum. This view nicely shows the flocculus, which, with the nodule \(a portion of the vermis\), comprises the flocculonodular lobe. The cerebellar tonsil pressing against the medulla is part of the cerebellar hemisphere. The trigeminal nerve \(V\) is shown, exiting the brainstem through the middle cerebellar peduncle."))
