Effect of adaptive plasticity of linear vestibulo-ocular reflex upon angular vestibulo-ocular reflex
Auris Nasus Larynx, 2000The vestibulo-ocular reflex (VOR) produces compensatory eye movements during head movements. The VOR consists of the angular VOR and the linear VOR. The VOR is under adaptive control that corrects VOR performance when visual-vestibular mismatch arises during head movements. Most experiments concerning plasticity of the VOR have used the angular VOR. So

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 ...

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 ...

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.

Archives of Neurology And Psychiatry, 1933
THE PROBLEM The actual anatomic foundations of the concept of the reflex arc were laid by Ramon y Cajal between 1887 and 1892, when he carried out a systematic study of the spinal cord with the method of Golgi. Cajal's findings were soon confirmed by the best neuro-anatomists (van Gehuchten, von Lenhossek, Held, Retzius, von Kolliker and others).1A ...

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 ...

Somatosensory input influences the vestibulo-ocular reflex
Neuroscience Letters, 2009To evaluate the influence of somatosensory input on the vestibulo-ocular reflex (VOR), we used sinusoidal rotation tests in 19 young, healthy volunteers. For the control condition, subjects were sinusoidally rotated in complete darkness and with eyes opened at a frequency of 0.2 Hz with a maximum angular velocity of 30 degrees /s for 30s, and at ...

The Vertical Vestibulo-Ocular Reflex
1982If 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 ...

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.

Vestibulo-ocular reflex pathways in internuclear ophthalmoplegia
Annals of Neurology, 1999We measured the vestibulo-ocular reflex (VOR) during head impulses in a patient with right-sided internuclear ophthalmoplegia. Head impulses are rapid, passive, high-acceleration, low-amplitude head rotations in the direction of a particular semicircular canal (SCC). Adduction of the right eye was abnormally slow during right lateral SCC head impulses.
