Eight astronauts were rotated in darkness about their longitudinal axis 20\u00b0 off vertical at low (0.125 Hz) and high (0.5 Hz) frequencies and their responses were compared before and after spaceflight. Eye movements were recorded using infrared videography and perceived motion was evaluated using a joystick with four degrees of freedom \u2013 pitch and roll tilt, front-back and lateral translation. Low-frequency OVAR generates tilt otolith-induced responses \u2013 modulation of ocular counter-roll and counter-pitch with perceived conical motion path \u2013 whereas high-frequency OVAR generates translational otolith-induced responses \u2013 modulation of horizontal and vergence slow phase velocity with perceived cylindrical motion path. While there were transient changes in the amplitude of the translational ocular responses on landing day, there were no major changes in the tilt ocular reflexes after adaptation to weightlessness. However, there was an increase in sensitivity to motion perception after spaceflight. Direct comparisons of pre- and postflight stimuli suggested that OVAR on landing day was less provocative of motion sickness than before spaceflight. These results confirm that some otolith reflexes elicited during passive motion may not be altered by short-duration spaceflight \u2013 or may readapt very quickly \u2013 and that the resolution of sensory conflict associated with postflight recovery involves higher-order neural processes.<\/jats:p>","DOI":"10.3233\/ves-130471","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T18:01:59Z","timestamp":1575309719000},"page":"13-22","source":"Crossref","is-referenced-by-count":18,"title":["Eye movements and motion perception during off-vertical axis rotation after spaceflight1"],"prefix":"10.1177","volume":"23","author":[{"given":"Gilles","family":"Cl\u00e9ment","sequence":"first","affiliation":[{"name":"International Space University, Strasbourg, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott J.","family":"Wood","sequence":"additional","affiliation":[{"name":"NASA Johnson Space Center, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","container-title":["Journal of Vestibular Research"],"original-title":[],"link":[{"URL":"https:\/\/content.iospress.com\/download?id=10.3233\/VES-130471","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T05:21:56Z","timestamp":1777612916000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/full\/10.3233\/VES-130471"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,3,28]]},"references-count":0,"journal-issue":{"issue":"1"},"URL":"https:\/\/doi.org\/10.3233\/ves-130471","relation":{"is-cited-by":[{"id-type":"doi","id":"10.3389\/fneur.2017.00414","asserted-by":"object"},{"id-type":"doi","id":"10.3389\/fphys.2018.01850","asserted-by":"object"}]},"ISSN":["1878-6464","0957-4271"],"issn-type":[{"value":"1878-6464","type":"electronic"},{"value":"0957-4271","type":"print"}],"subject":[],"published":{"date-parts":[[2013,3,28]]}}}
