WebbThe Annals of otology, rhinology, and laryngology. 1981. TLDR. The velocity difference between saccades and quick phases probably reflects different pontine mechanisms while the somewhat higher velocity in quick phase of Vestibular nystagmus recorded in light is probably related to higher attention evoked by vestibular-visual interaction. 13.

Webb1 jan. 2003 · Downbeat nystagmus (DN), a fixation nystagmus with the fast phases directed downward, is usually caused by cerebellar lesions, but the precise etiology is … WebbFoveating fast phases were generated during lower slow-phase velocities whereas, defoveating fast phases occurred during higher slow-phase velocities. The bidirectional model simulated Alexander's law behavior under all viewing and fixation conditions. Our ocular-motor model accurately simulates LMLN-patient ocular motility data and provides … WebbAs you know, we named a nystagmus for the fast phase; so a down-beat beats down- a slow phase up followed by a downbeat fast phase - so slow and fast. So the fast phase and down made is towards down. It'll also be worse when you look down - that's Alexander's law. So downbeat nystagmus localizes to cervical medullary junction and even though ... desert flower hotel taos
