Web1 aug. 2000 · As expected for an oscillation originating in the CNS and propagated along similar binocular pathways, the same 10-Hz rhythm is present in the two eyes with zero phase offset. It is noteworthy that the smooth eye modulation is reminiscent of the similar frequency CNS modulation of smooth slow finger movements described by Vallbo and … Web1 apr. 2004 · Nystagmus is an involuntary back-and-forth motion of both eyes. Any nystagmus due to vestibular stimulation or pathology is composed of slow and fast eye movements. The slow component (slow eye velocity) is produce by the intact ear, which generates a normal VOR as a result of the asymmetry between the discharge rates of …

WebNystagmus is a rhythmic regular oscillation of the eyes with low velocities in at least one direction. Nystagmus can be sorted into two groups by appearance. a) Pendular nystagmus has a sinusoidal oscillation without fast phases. This is divided into a number of subtypes, based on associated conditions and special idiosyncratic trajectories. Web1 mei 2003 · Motion perception during involuntary eye vibration.

Nystagmus What it is, causes and treatments
Web10 feb. 2015 · Purpose: Infantile nystagmus (IN) is a pathological, involuntary oscillation of the eyes consisting of slow, drifting eye movements interspersed with rapid reorienting quick phases. The extent to which quick phases of IN are programmed similarly to saccadic eye movements remains unknown. We investigated whether IN quick phases exhibit … WebMiosis (pupillary constriction): A loss of sympathetic input causes unopposed parasympathetic stimulation which leads to pupillary constriction. This degree of miosis may be subtle and require a dark room. Anhidrosis (decreased sweating): Also caused by a loss of sympathetic activity. The pattern of anihidrosis may help identify the lesion.
