Section of mid-brain at level of superior colliculi. Hind- and mid-brains; postero-lateral view. Superior colliculus labeled in blue. The superior colliculus is a paired structure of the dorsal midbrain and is part of the midbrain tectum. The two superior colliculi are situated inferior/caudal to the pineal gland and the splenium of corpus ...
It consists of groups of nerve cells-grey matter scattered in white matter. It basically connects the forebrain and the hind brain. It has four corpora quadrigemina which are the reflex centres of eye movement and auditory responses. The superior part of corpora quadrigemina are called superior colliculi, and inferior part as inferior colliculi ...

7 and 8 are the four colliculi. The midbrain is the shortest segment of the brainstem, measuring less than 2cm in length. It is situated mostly in the posterior cranial fossa, with its superior part extending above the tentorial notch. [2]

The collicular artery originates from P1 segment of the posterior cerebral artery near the side of interpeduncular fossa. [2] It arises just distal to the bifurcation of the basilar artery. It runs posteriorly along the cerebral peduncle passing the crural and ambient cisterns.
The anterior commissure works with the posterior commissure to link the two cerebral hemispheres of the brain and also interconnects the amygdalae and temporal lobes, contributing to the role of memory, emotion, speech and hearing. It also is involved in olfaction, instinct, and sexual behavior.
The NOT consists of relatively large cells and is located between the superior colliculi. The ON is located medial to the NOT and has a tail that extends between the NOT and NPP, which is ventral to the ON. [10] Two additional nuclei have also been identified: the posterior limitans (PLi) and the commisural pretectal area (CPA). [12]
