Adaptation to Vestibular Disorientation. Iii. Influence on Adaptation of Interrupting Nystagmic Eye Movements with Opposing Stimuli

摘要

Failure of adaptation of nystagmic eye movements to occur under certain conditions of stimulation by angular acceleration has been ascribed to a failure to allow the eye-movement response to run its course. In this study, 3 groups of subjects were tested under conditions of repeated angular accelerations in which Group A received unidirectional stimulation, Group B received bidirectional stimulation with both responses allowed to run their course, and Group C received bidirectional stimulation but the response in one direction was interrupted. Adaptation occurred for all groups in spite of the different test procedures. Other implications of the results are discussed. (Author)
