Abstract : Electronystagmographic (ENG) recordings of vertical vestibular nystagmus induced by Coriolis stimulation are influenced by certain factors. Four factors studied were: eyes open in a state of reverie; eyes open in a state of alertness, the subject mentally working arithmetic problems; eyes closed in a state of reverie; eyes closed in a state of alertness, the subject mentally working arithmetic proglems. These factors influence the decay function and the sensitivity of nystagmic responses to Coriolis stimulation. For this reason when presenting nystagmic recordings as a result of rotation, it is important to indicate the conditions and the environment to which a subject is exposed during the recordings.
