title: A Z-axis recumbent rotating device for use in parabolic flight.
abstract: A prototype apparatus for exposing persons to rotation about their Z-axis in parabolic flight is described. Although it resembles Earth-horizontal axis devices, added features are its strength and portability, and the fiber glass "couch" with adjustable elements providing support and restraint. Even under ground-based conditions, this device provides unique opportunities for investigations involving not only canalicular and macular mechanoreceptors, but also touch, pressure, and kinesthetic receptor systems.
