Adaptation to bizarre stimulation of the semicircular canals as indicated by the oculogyral illusion.

Abstract

Abstract : Four healthy male subjects 19 to 23 years of age were exposed to tilt in a specially constructed chair mounted in a rotating room which is built around the center of a human centrifuge. Determinations of the course of the adaptation to the oculogyral illusion are reported. Also compared are the effects of their voluntary head movements. Information obtained appears to have application to anticipated problems in manned orbiting satellites and to any rotating installation where personnel will be exposed to angular velocities above 2.0 rpm.
