THE APPEARANCE OF COMPENSATORY NYSTAGMUS IN HUMAN SUBJECTS AS A CONDITIONED RESPONSE DURING ADAPTATION TO A CONTINUOUSLY ROTATING ENVIRONMENT
Abstract
Seven men lived in a rotating room (5.4 RPM) for 64 hours. Controlled tests before and during this interval demonstrated that Coriolis vestibular phenomena including Coriolis nystagmus diminished markedly. A compensatory nystagmus, induced by head or whole body movements, was recorded more than one hour after the rotation had ceased. Factors of possible significance in conditioning the compensatory nystagmus are: (1) otolith and proprioceptor sensory influx prior to and during discordant canal input; (2) a consistent sensory influx for each stimulusproducing movement; (3) intention in stimulusproducing movements; and (4) visual inhibition. Contributions of compensatory and arousal factors to vestibular suppression are considered in relation to practical problems of transfer of habituation from one acceleration environment to another.
