Physiological Nystagmus in the Cat*†
Journal of the Optical Society of America, 1960Cats were prepared by the encephale isole technique. A small plane-mirror mount was sutured to each cornea without obstructing vision, and eye movements were recorded using the optical-lever method. The records showed physiological nystagmus similar to that in man, although the cats had fewer and smaller saccades.

THE PHYSIOLOGY OF VESTIBULAR NYSTAGMUS
Archives of Otolaryngology - Head and Neck Surgery, 1929Vestibular nystagmus is an intricate physiologic phenomenon. This is due to the incomplete knowledge of the subject but will still be true when the knowledge is complete, because of the complexity of the mechanisms involved. The phenomenon has long attracted the interest of the physiologist because of the importance of the eyes and their compensatory ...

We wanted to ascertain whether a physiological horizontal vestibular spontaneous nystagmus is existent, or whether the spontaneous and positional nystagmus seen in clinically healthy persons in the electronystagmogram -- when fixation had been excluded completely -- was always the result of earlier damages to the vestibular system (Jatho).

Relating a Component of Physiological Nystagmus to Visual Display
Science, 1960A transactional position suggests the hypothesis that there should be changes in the fine eye movements of a fixating subject if the fixated visual display is altered. It is shown that the mean saccadic eye movements are unequivocally different with different positions of the stimulus within the visual field.

[Origin and physiology of the vestibular nystagmus].
Vestnik otorinolaringologii, 1997Oculomotor reactions in tracing moving visual objects by moving eyes and head were studied in 30 healthy subjects. With changing speed of the moving objects, electrooculogram registrating eye movements acquired the form of the vestibular nystagmus. The amplitude and frequency of the nystagmic movements were defined through the object's acceleration ...

PHYSIOLOGICAL MECHANISMS OF THE NYSTAGMUS PRODUCED BY ROTATIONS ABOUT AN EARTH‐HORIZONTAL AXIS*
Annals of the New York Academy of Sciences, 1981The physiological basis of the nystagmus produced by rotation about an earth-horizontal axis is investigated with particular emphasis on the unidirectional nystagmus attributed to a bias component. Eye movement recordings were made with dc electro-oculography in alert squirrel monkeys and afferent responses were recorded from semicircular canals and ...

Acta Oto-Laryngologica, 1966
Three guinea-pigs were administered injections of 3 cc of 0.3% procaine solution into the superficial and the deep group of the nuchal muscles respectively, and the optic head and eye nystagmus were observed before and after the injection. Procainization of the superficial group of the nuchal muscles was not found to influence seriously the occurrence ...

The video head impulse test during post-rotatory nystagmus: physiology and clinical implications
Experimental Brain Research, 2015The aim of this study was to test the effects of a sustained nystagmus on the head impulse response of the vestibulo-ocular reflex (VOR) in healthy subjects. VOR gain (slow-phase eye velocity/head velocity) was measured using video head impulse test goggles.

[Physiologic and pathologic rebound nystagmus. Description and comparison].
Fortschritte der Ophthalmologie : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 1991Using a binocular, infrared charged coupled device (CCD), an eye tracker coupled with an Olivetti M24 PC (resolution up to 0.1 degrees, scanning with 80 frames/s), the eye movements of 20 normal individuals with normal visual acuity and binocular function were recorded to detect physiological endpoint (EPN) and rebound nystagmus (RN).

[Physiological nature and diagnostic implications of rotational nystagmus].
Vestnik otorinolaringologii, 2010The authors provide a rationale for clinical studies of four types of rotational nystagmus, true vestibular, cervico-vestibular, opto-vestibular, and cervico-optovestibular. A physiological concept of nystagmus during active head rotation is formulated. Negative consequences of vestibular nystagmus as a pathophysiological reaction are discussed.
