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.

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.

Signal processing in the vestibulo-ocular reflex
2022In this chapter, Robinson develops models to account for the neural control of the vestibulo-ocular reflex in response to horizontal and vertical head rotations. By combining knowledge of the discharge properties of the several subpopulations of neurons that contribute to vestibular eye movements with their known anatomical connections, these models ...

The vestibulo-ocular reflex in three dimensions
Experimental Brain Research, 2002The purpose of this paper is to review the kinematics and dynamics of the vestibulo-ocular reflex (VOR) in three dimensions. We give a brief, didactic tutorial on vectors and matrices and their importance as representational schemes for describing the kinematics and dynamics of the angular and linear accelerations that activate the vestibular system ...

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.

Plasticity and repair of the vestibulo-ocular reflex
2022It is self-evident, once one thinks about it, that the vestibulo-ocular reflex must have caretaker systems that keep it operating correctly over the span of a lifetime. When a movement is not correct (e.g., in position, speed, direction) it is said to be dysmetric. For the vestibulo-ocular reflex (VOR), if eye velocity is not equal and opposite to head

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 ...

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.

Organization and Control of the Vestibulo-Ocular Reflex
1979Publisher Summary Two generations of vestibulo-ocular reflex (VOR) models can be distinguished. This chapter describes a first generation model of VOR. The first generation models describe the VOR as an isolated system with uncontrollable characteristics.

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 ...
