[Normal vertical vestibulo-ocular reflexes in man].
The vertical vestibular-ocular reflexes (VVOR) were evaluated in 22 human test subjects aged 18-47 years. The VVOR were evoked by active head movements in the sagittal plane with the frequencies of 0.04 Hz (stimulus 1), 0.12 Hz (stimulus 2), and 0.24 Hz (stimulus 3). Records were made either with eyes closed (Program I) or fixed at an object (Program II). In the norm, the interocular asymmetry was absent and there was an insignificant prevalence of upward VVOR. As was noted, VVOR were largely subdued in the condition of gaze fixation; this was particularly true with the downward vertical vestibular-ocular reflexes.
