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 ventral-most pair (K1 and K2) appears closely tied to the function of the superior colliculus. K cells are not restricted to the koniocellular layers. They are also found in small groups, in pairs or as single cells within M and P layers. Larger subpopulations form bridges spanning the distance between two adjacent K layers. [1]: 131

The tectopulvinar pathway is a fast-acting pathway that provides the viewer with information on the absolute spatial information of objects. The pathway plays a large role in directing visual spatial attention and is particularly responsive to novel stimuli that appear or move in peripheral vision; however, because it receives mostly magnocellular visual input, the tectopulvinar pathway is not ...
In humans, the tectospinal tract (or colliculospinal tract) is a decussating extrapyramidal tract that coordinates head/neck and eye movements. [1]It arises from the superior colliculus of the mesencephalic (midbrain) tectum, and projects to the cervical and upper thoracic spinal cord levels. [2]
Unlike the midbrain tectum (which is a sensory structure located posteriorly), the midbrain tegmentum, which locates anteriorly, is related to a number of motor functions. Within the tegmentum, the red nucleus is in charge of motor coordination (specifically for limb movements) and the periaqueductal gray matter (PAG) contains critical circuits ...
IC = Inferior colliculus EE (Excitatory excitatory) type neurons are characterized by excitatory responses to monaural stimulations of both ears. This response may either be higher than the monaural response (EE– facilitation) Or lower (EE– occlusion)
The paired nuclei are posterior to the main motor nucleus (oculomotor nucleus) and anterolateral to the cerebral aqueduct in the rostral midbrain at the level of the superior colliculus. It is the most rostral of the parasympathetic nuclei in the brain stem .
