Velocity storage: its multiple roles

Journal of Neurophysiology, 2020
Our research described in this article was motivated by the puzzling finding of the Skylab M131 experiments: head movements made while rotating that are nauseogenic and disorienting on Earth are innocuous in a weightless, 0- g environment. We describe a series of parabolic flight experiments that directly addressed this puzzle and discovered the ...

Characteristics of eye velocity storage during periods of suppression and reversal of eye velocity in monkeys

Experimental Brain Research, 1986
An eye velocity storage mechanism has been postulated in the vestibulo-optokinetic system to account for the prolongation of vestibular nystagmus (VN) and the occurrence of optokinetic after-nystagmus (OKAN). Presentation of a subject-stationary full-field surround during VN and OKAN (= full-field fixation) rapidly reduces activity related to eye ...

Effects of midline medullary lesions on velocity storage and the vestibulo-ocular reflex

Experimental Brain Research, 1991
1. Crossing fibers were sectioned at the midline of the medulla caudal to the abducens nucleus in four cynomolgus monkeys. In two animals the lesions caused the time constant of horizontal and vertical per- and post-rotatory nystagmus to fall to 5-8 s. The slow rise in optokinetic nystagmus (OKN), as well as optokinetic after-nystagmus (OKAN) and cross-

Multisensory Integration in the Human Vestibular Velocity Storage Mechanism?

Acta Oto-Laryngologica, 1991
To test the hypothesis that auditory inputs can interact with the optokinetically or vestibularly-charged human VSM, we examined the effects of sound on rotational nystagmus and HOKAN. Subjects were rotated at 60 degrees/s, in either clockwise (CW) or counterclockwise (CCV) direction, for a total of 3 min.
