  2. Superior colliculus - Wikipedia

    en.wikipedia.org/wiki/Superior_colliculus

    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.

  3. Corpora quadrigemina - Wikipedia

    en.wikipedia.org/wiki/Corpora_quadrigemina

    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 ...

  4. Frontal eye fields - Wikipedia

    en.wikipedia.org/wiki/Frontal_eye_fields

    The FEF constitutes together with the supplementary eye fields (SEF), the intraparietal sulcus (IPS) and the superior colliculus (SC) one of the most important brain areas involved in the generation and control of eye movements, particularly in the direction contralateral to the frontal eye fields' location. In addition, FEF has an important ...

  5. Red nucleus - Wikipedia

    en.wikipedia.org/wiki/Red_nucleus

    The red nucleus or nucleus ruber is a structure in the rostral midbrain involved in motor coordination. [1] The red nucleus is pale pink, which is believed to be due to the presence of iron in at least two different forms: hemoglobin and ferritin. [2]

  6. Pretectal area - Wikipedia

    en.wikipedia.org/wiki/Pretectal_area

    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]

  7. Supplementary eye field - Wikipedia

    en.wikipedia.org/wiki/Supplementary_eye_field

    [2] [3] The SEF constitutes together with the frontal eye fields (FEF), the intraparietal sulcus (IPS), and the superior colliculus (SC) one of the most important brain areas involved in the generation and control of eye movements, particularly in the direction contralateral to their location. [2] [4] Its precise function is not yet fully known ...

  8. Midbrain - Wikipedia

    en.wikipedia.org/wiki/Midbrain

    The corpora quadrigemina are four mounds, called colliculi, in two pairs – a superior and an inferior pair, on the surface of the tectum. The superior colliculi process some visual information, aid the decussation of several fibres of the optic nerve (some fibres remain ipsilateral), and are involved with saccadic eye movements.

  9. Lateral geniculate nucleus - Wikipedia

    en.wikipedia.org/wiki/Lateral_geniculate_nucleus

    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 ...
