Inferior colliculus, the principal midbrain nucleus of the auditory pathway Superior colliculus , a paired structure that forms a major component of the vertebrate midbrain Collicular arteries , which supply portions of the midbrain
The brachium of superior colliculus (or superior brachium) is a branch that extends laterally from the superior colliculus, and, passing to the thalamus between the pulvinar and the medial geniculate nuclei, is partly continued into an eminence called the lateral geniculate nucleus, and partly into the optic tract.
The nuclei of two pairs of cranial nerves are similarly located at the ventral side of the periaqueductal grey – the pair of oculomotor nuclei (which control the eyelid, and most eye movements) is located at the level of the superior colliculus, [10] while the pair of trochlear nuclei (which helps focus vision on more proximal objects) is ...

The inferior colliculi of the midbrain are located just below the visual processing centers known as the superior colliculi. The inferior colliculus has three subdivisions – the central nucleus, the dorsal cortex by which it is surrounded, and an external cortex which is located laterally. [ 1 ]
The principal neurons in the LGN receive strong inputs from the retina. However, the retina only accounts for a small percentage of LGN input. As much as 95% of input in the LGN comes from the visual cortex, superior colliculus, pretectum, thalamic reticular nuclei, and local LGN interneurons.

The facial colliculus is an elevated area located in the pontine tegmentum (dorsal pons), [citation needed] within the floor of the fourth ventricle (i.e. the rhomboid fossa). It is formed by fibres from the facial motor nucleus looping over the abducens nucleus. The facial colliculus is an essential landmark of the rhomboid fossa. [1]
