Abstract
A method is described for the analysis of nystagmus evoked by a pseudorandom rotational stimulus composed of a summation of sinusoidal components. This method allows for the rapid identification of the dynamic response properties of vestibulo-ocular and visual-vestibulo-ocular reflexes over a wide bandwidth. The results of applying the technique to VOR eye movements evoked by rotation about a vertical axis in the dark are shown and discussed, as well as VVOR, VOR, and OKR (optokinetic reflex) gain and phase data derived from responses to pseudorandom rotation
