An active efficient coding model of the optokinetic nystagmus
Optokinetic nystagmus (OKN) is an involuntary eye movement responsible for stabilizing retinal images in the presence of relative motion between an observer and the environment. Fully understanding the development of optokinetic nystagmus requires a neurally plausible computational model that accounts for the neural development and the behavior. To date, work in this area has been limited. We p...
متن کاملStudy of congenital nystagmus: optokinetic nystagmus.
A severe defect of optokinetic nystagmus (OKN) was found in 46 patients with congenital nystagmus. Abnormal patterns of OKN, such as superimposition of pendular oscillations on the optokinetic slow component and inversion of OKN, were observed. Optokinetic gain (eye movement velocity/drum velocity) was decreased compared to that in normal subjects, and optokinetic after-nystagmus, or transient ...
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 کاملVertical 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 کاملSpontaneous Nystagmus in the Dark in an Infantile Nystagmus Patient May Represent Negative Optokinetic Afternystagmus
Abnormal projection of the optic nerves to the wrong cerebral hemisphere transforms the optokinetic system from its usual negative feedback loop to a positive feedback loop with characteristic ocular motor instabilities including directional reversal of the optokinetic nystagmus (OKN) and spontaneous nystagmus, which are common features of infantile nystagmus syndrome (INS). Visual input plays ...
