The Vestibulo-Ocular Reflex and Seasickness Susceptibility
Journal of Vestibular Research, 1996VOR parameters were compared in subjects at the extremes of the seasickness susceptibility scale. Thirty-nine subjects highly susceptible to seasickness and 30 nonsusceptible subjects participated in the study. The VOR was evaluated by the Sinusoidal Harmonic Acceleration (SHA) test at frequencies of 0.01, 0.02, 0.04, 0.08, and 0.16 Hz.

Identification of the vestibulo-ocular reflex dynamics
2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014The vestibulo-ocular reflex (VOR) plays an important role in our daily activities by enabling us to fixate on objects during head movements. Modeling and identification of the VOR improves our insight into the system behavior and helps in diagnosing various disorders.

The Vertical Vestibulo-Ocular Reflex [PDF]
, 1982 If causal and teleological reasoning were clearly diametrically opposed attitudes, then tackling the central organization of vertical eye movements would indeed be a formidable task. This opening, and light, assertion is partially explained by the subsequent lengthy introduction to some of the problems posed by the descriptive, but unfortunately ...

The vertical vestibulo-ocular reflex and ocular resonance
Vision Research, 1984A technique is described for the measurement of retinal image motion under conditions of forced angular vibration of the head in pitch at frequencies between 10 and 100 Hz. The experimental technique has been used in nine normal subjects, and in two subjects with vestibular dysfunction; one with unilateral, the other with bilateral deficit.

A vestibulo-ocular reflex with no head movement
Biological Cybernetics, 1986Eye movements were produced in an elasmobranch preparation by electrical stimulation of the horizontal canal ampullary nerves. A pseudorandom binary sequence of stimulus pulse trains was delivered bilaterally. Eye position during this stimulus was cross-correlated with the stimulus pattern to obtain a linear model of the response.

Learning and Memory in the Vestibulo-Ocular Reflex
Annual Review of Neuroscience, 1995Studies of the neural basis of learning and memory in intact animals must, by their nature, start "from the top" by choosing a behavior that can be modified through learning, revealing how iaeuronal activity gives rise to that behavior, and then investigating, in the awake, behaving animal, changes in neural signaling that are associated with learning.

The vestibulo-ocular reflex (VOR) ensures best vision during head motion by moving the eyes contrary to the head to stabilize the line of sight in space. The VOR has three main components: the peripheral sensory apparatus (a set of motion sensors: the semicircular canals, SCCs, and the otolith organs), a central processing mechanism, and the motor ...

Gravity and the vertical vestibulo-ocular reflex
Experimental Brain Research, 1991We studied the vertical vestibulo-ocular reflex (VOR) and vertical visual-vestibular interaction induced by voluntary pitch in the upright and onside positions in eight normal human subjects. Subjects were trained to produce sinusoidal (0.4 to 1.6 Hz) pitch head movements guided by a frequency modulated sound signal.

Effects of halothane on the vestibulo-ocular reflex
American Journal of Otolaryngology, 1980The differential effect of halothane on the characteristics of fast and slow components of vestibular nystagmus was investigated in rabbits. Eye movements were monitored using the "magnetic search coil" method and evaluated with the aid of a laboratory minicomputer. Low concentrations of halothane act preferentially on the fast component.

Asymmetry of Vestibulo‐Ocular Reflex in the Cat
Otolaryngology–Head and Neck Surgery, 1985Vertical eye movements were recorded in alert, restrained cats that were subjected to whole‐body rotations which stimulated the vertical semicircular canals. The results showed a significant asymmetry between the upward and downward slow‐phase eye movements, which suggests differences in the CNS processing of vertical canal inputs vis‐à‐vis the ...
