## Abstract Parkinson's disease (PD) is associated with a number of oculomotor deficits; however, little is known about changes in vertical optokinetic nystagmus (OKN) associated with PD. We recorded eye movements in 14 PD patients and 14 ageβmatched controls in response to large field OKN stimulat
Horizontal and vertical OKN and OKAN were recorded in four conditions using the EOG technique. Instructions to subjects were aimed at obtaining a "look" type OKN. Two optokinetic stimulators, a stationary sphere and a binocular portable model, were compared with the subject in the upright condition.
Horizontal optokinetic nystagmus (OKN) evoked by a random dot pattern moving at a constant speed around the animal was investigated in wildtype mice and "Weaver" mutants (cerebellar impairment) by means of chronically implanted EOG-electrodes. The shape of OKN in the homozygotic Weaver mouse was cle
