WebApr 11, 2024 · Tau expression follows RGCs axonal tracts up to the superior colliculi. RGCs' axons form the optic nerve and these cells project directly into the brain. The superior colliculus is the main relay for these cells in the brain. Therefore, we assessed the distribution pattern of GFP and Tau further down the visual pathway. Websensory stimulus from affected pathway to the midbrain is reduced unaffected pupil will dilate from its constricted state when light is moved from the unaffected to the affected …

WebFeb 14, 2024 · A unilateral lesion in the pretectal nucleus or in the brachium of the superior colliculus will damage the pupillary fibers coming from the ipsilateral optic tract. This can produce a contralateral RAPD, just like in optic tract lesions, but without any visual loss or visual field defect. WebThe superior colliculus receives input from the retina and the visual cortex and participates in a variety of visual reflexes, particularly the tracking of objects in the contralateral visual field. The inferior colliculus receives both crossed and uncrossed auditory fibres and projects upon the medial geniculate… Read More Webthe superior colliculus of the midbrain - for control of eye movements; the pretectum of the midbrain - for control of the pupillary light reflex; and the suprachiasmatic nucleus of the hypothalamus - for control of diurnal rhythms and hormonal changes.
