We aimed to describe the psychophysiological changes accompanying visually induced motion sickness, using a motion video, hypothesizing that differences would be evident between subjects who developed nausea in comparison to those who did not. A motion, or a control, stimulus was presented to 98 healthy subjects in a randomized crossover design. Validated questionnaires and a visual analogue scale (VAS) were used for the assessment of anxiety and nausea. Autonomic and electrogastrographic activity were measured at baseline and continuously thereafter. Plasma vasopressin and ghrelin were measured in response to the motion video. Subjects were stratified into quartiles based on VAS nausea scores, with the upper and lower quartiles considered to be nausea sensitive and resistant, respectively. Twenty\u2010eight subjects were exposed to the motion video during functional neuroimaging. During the motion video, nausea\u2010sensitive subjects had lower normogastria\/tachygastria ratio and cardiac vagal tone but higher cardiac sympathetic index in comparison to the control video. Furthermore, nausea\u2010sensitive subjects had decreased plasma ghrelin and demonstrated increased activity of the left anterior cingulate cortex. Nausea VAS scores correlated positively with plasma vasopressin and left inferior frontal and middle occipital gyri activity and correlated negatively with plasma ghrelin and brain activity in the right cerebellar tonsil, declive, culmen, lingual gyrus and cuneus. This study demonstrates that the subjective sensation of nausea is associated with objective changes in autonomic, endocrine and brain networks, and thus identifies potential objective biomarkers and targets for therapeutic interventions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1113\/jphysiol.2014.284240","type":"journal-article","created":{"date-parts":[[2015,1,2]],"date-time":"2015-01-02T06:42:15Z","timestamp":1420180935000},"page":"1183-1196","source":"Crossref","is-referenced-by-count":86,"title":["Visually induced nausea causes characteristic changes in cerebral, autonomic and endocrine function in humans"],"prefix":"10.1113","volume":"593","author":[{"given":"Adam D.","family":"Farmer","sequence":"first","affiliation":[{"name":"Centre for Digestive Diseases Blizard Institute Wingate Institute of Neurogastroenterology Barts and the London School of Medicine &amp; Dentistry Queen Mary University of London  London E1 2AJ UK"},{"name":"University Hospitals of North Midlands  Stoke on Trent Staffordshire ST4 6QG UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vin F.","family":"Ban","sequence":"additional","affiliation":[{"name":"Centre for Digestive Diseases Blizard Institute Wingate Institute of Neurogastroenterology Barts and the London School of Medicine &amp; Dentistry Queen Mary University of London  London E1 2AJ UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven J.","family":"Coen","sequence":"additional","affiliation":[{"name":"Centre for Digestive Diseases Blizard Institute Wingate Institute of Neurogastroenterology Barts and the London School of Medicine &amp; Dentistry Queen Mary University of London  London E1 2AJ UK"},{"name":"Department of Neuroimaging Institute of Psychiatry King's College London  London SE5 8AF UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gareth J.","family":"Sanger","sequence":"additional","affiliation":[{"name":"Centre for Digestive Diseases Blizard Institute Wingate Institute of Neurogastroenterology Barts and the London School of Medicine &amp; Dentistry Queen Mary University of London  London E1 2AJ UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gareth J.","family":"Barker","sequence":"additional","affiliation":[{"name":"Department of Neuroimaging Institute of Psychiatry King's College London  London SE5 8AF UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"Gresty","sequence":"additional","affiliation":[{"name":"Medical Research Council Spatial Disorientation Group Department of Medicine Imperial College London  London SW7 2BX UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincent P.","family":"Giampietro","sequence":"additional","affiliation":[{"name":"Department of Neuroimaging Institute of Psychiatry King's College London  London SE5 8AF UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven C.","family":"Williams","sequence":"additional","affiliation":[{"name":"Department of Neuroimaging Institute of Psychiatry King's College London  London SE5 8AF UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominic L.","family":"Webb","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences Uppsala University  Box 256 751 05 Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Per M.","family":"Hellstr\u00f6m","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences Uppsala University  Box 256 751 05 Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul L.
