Vertical optokinetic nystagmus and optokinetic afternystagmus in humans.
Vertical optokinetic nystagmus (OKN) and optokinetic afternystagmus (OKAN) were recorded in 6 normal subjects using the magnetic scleral search coil technique in order to reevaluate the up-down symmetry of these responses. The effects of body position relative to gravity were investigated by comparing OKN and OKAN elicited with the subjects in an erect and in a lateral side position. No consist...
متن کاملScotopic Optokinetic Nystagmus Thresholds
Although it is now well established that a variety of ocular and systemic diseases, including diabetes, are harmful to the SWS cone pathway, causing a decrease in SW sensitivity,"the site(s) of the loss is not well known. The loss in SW sensitivity in diabetes has been variously attributed to changes in the lens, loss of SWS cone receptors due to their greater vulnerability to insult, the reduc...
متن کاملOptokinetic memory in the locust.
Having established that a crab can retain a visual impression of the positions of contrasting stripes in its visual field for a period of many minutes in the dark with an accuracy of about ^ ° over short periods, it became of immediate interest to know whether other arthropods can do the same. The same technique as in the previous papers (Horridge, 1966 a) was therefore applied to the locust as...

متن کاملOtolith deprivation induces optokinetic compensation.
According to the multisensory integration theory vestibular, optokinetic and proprioceptive inputs act in concert to maintain a stable retinal image of the visual world. Yet, it remains elusive to what extent the otolith organs contribute to this process and whether a specific loss of otolith input is compensated for. Here we investigated the compensatory eye movements in tilted mice, which lac...
