Dissection of sheep brain
(dorsal cerebrum removed to expose the brainstem). The
thalamus is marked bilaterally (pink pics). The green pick pokes through the third ventricle and into the
interthalamic adhesion. The sheep pineal body (yellow) is large compared to that of the dog. Red picks mark habenular nuclei of the epithalamus. For a ventral view of the diencephalon, click

Some non-diencephalic structures are indicated: caudate nucleus (orange), hippocampus (blue), and rostral colliculus (white) of the midbrain.
