AROUSAL EFFECTS AND NYSTAGMUS DURING PROLONGED CONSTANT ANGULAR ACCELERATION

Abstract

WHEN TASKS WERE ASSIGNED TO INSURE HEIGHTENED MENTAL ACTIVITY, VESTIBULAR NYSTAGMUS DID NOT DECLINE DURING CONSTANT ANGULAR ACCELERATION. With the same vestibular stimulus but with a task not conducive to heightened mental activity, nystagmus declined (or was of very low magnitude) during the stimulus. It is suggested that previously reported losses of subjective velocity during constant angular acceleration, may be an indicator of reduced corticofugal feedback to the reticular system and hence, as subjective velocity declines in this situation, nystagmus also declines except for extraneous sources of arousal.
