where is the superior colliculus located in the brain
Superior colliculus The two superior colliculi sit below the thalamus and surround the pineal gland in the vertebrate midbrain. It comprises the dorsal aspect of the midbrain, posterior to the periaqueductal gray and immediately superior to the inferior colliculus. The inferior and superior colliculi are known collectively as the corpora quadrigemina (Latin, quadruplet bodies). The brachium of superior colliculus (or superior brachium) extends laterally from the superior colliculus, and, passing between the pulvinar and medial geniculate body, is partly continued into an eminence called the lateral geniculate body, and partly into the optic tract.
