The superior colliculus is a synaptic layered structure. The two superior colliculi sit below the thalamus and surround the pineal gland in the mammalian 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 for quadruplet bodies). The superior colliculi are larger than the inferior colliculi, though th… WebThe average thickness of the superior and inferior colliculi was about 5 mm, but the range was from 2-7 mm on the midline sagittal section. Abnormally thin colliculi appeared to have no clinical significance while abnormal thickness was observed in patients with neoplastic disease, sarcoidosis, and mesencephalic "beaking."
