Vestibulo-Oculomotor Reflex (VOR) EXPLAINED

The video tutorial explains the vestibulo-ocular reflex (VOR), a mechanism that stabilizes gaze during head movements. It involves cranial nerves and semicircular canals, with separate pathways for horizontal and vertical VOR. The horizontal VOR allows eye movement opposite to head rotation, using lateral semicircular canals, while the vertical VOR uses superior canals for up-down head movements. Neural pathways and muscle activations are detailed, highlighting the role of rectus muscles. Testing methods like the head thrust test are discussed, along with potential disorders such as vestibular deficits and Meniere's disease.
