Adaptation to Prolonged Constant Angular Acceleration

Abstract

Two independent groups of normal human subjects were exposed to a number of long-duration (up to 96 sec), relatively high-intensity (3d`/ sec<sup>2</sup>-24d`/sec²), constant, angular accelerations. Nystagmic decrements during stimulation were clearly evident. The decrements were initiated at about the same time after stimulus onset (28–32 sec) for all accelerations used. The decrements in the nystagmic responses were compared to related findings for both subjective and electrophysiological responses.
