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. [citation needed]
The pulvinar also has input from the superior colliculus to inferior, lateral and medial sections, which seems to be important in the initiation and compensation of saccade, [4] [5] as well as the regulation of visual attention [6] [7]
It represents the rostral continuation of the pulvinar ... superior parietal lobule, pretectal area, and superior colliculus. [1] Efferents
Lateral pulvinar nucleus, together with its inferior and medial nuclei, receives afferent input from superior colliculus. [1] [2] The dorsal part of the lateral pulvinar nucleus also receives afferent input from posterior parietal cortex and the dorsal stream cortical areas. [1] [2]
As much as 95% of input in the LGN comes from the visual cortex, superior colliculus, pretectum, thalamic reticular nuclei, and local LGN interneurons. Regions in the brainstem that are not involved in visual perception also project to the LGN, such as the mesencephalic reticular formation, dorsal raphe nucleus, periaqueuctal grey matter, and ...
Medial pulvinar nucleus, together with its lateral and inferior nuclei, receives afferent input from superior colliculus. [1] [2]Medial pulvinar nucleus also receives many afferent inputs from different cortical areas, including cingulate, posterior parietal, premotor and prefrontal cortical areas.
In neuroanatomy, the pretectal area, or pretectum, is a midbrain structure composed of seven nuclei and comprises part of the subcortical visual system.Through reciprocal bilateral projections from the retina, it is involved primarily in mediating behavioral responses to acute changes in ambient light such as the pupillary light reflex, the optokinetic reflex, and temporary changes to the ...
