1. Physiology Being an involuntary action or response, such as a sneeze, blink, or hiccup. Objectives: 1) To compare the incidence of elevated visually enhanced vestibular‐ocular reflex (VVOR) rotational gain during rotational chair testing in a normal control group versus a group of patients diagnosed with migraine vestibulopathy; 2) to discuss the possible application of VVOR gain during rotational chair testing for diagnosing migraine vestibulopathy. Unlike the vestibulo-ocular reflex, the optokinetic reflex does not require the sensing of balance changes… only visual changes. So if you don’t see anything, like in the dark or if your eyes are closed, then you don’t have optokinetic nystagmus.

Most of the chapters contain a description of the sign, associated signs, and cases, supported by clinical videos and figures.

In VOR the semicircular canals of the inner ear measure rotation of the head and provide a signal for the oculomotor nuclei of the brainstem, which innervate the eye muscles. Recent animal and clinical studies on the vestibulo-ocular reflex deal with a number of physiological and clinical aspects from which three were chosen for this review: (1) the torsional vestibulo-ocular reflex and its disorders; (2) the otolith contribution to the vestibulo-ocular reflex; and (3) n … Vestibulo-okulära reflexen - då huvudet rör sig måste ögonen röra sig åt motsatt håll för att inte synintrycket skall bli skakigt och omöjligt att extrahera information utifrån.
