Editing Motion sickness (section)

====Centrifuge motion sickness====
Rotating devices such as [[Centrifuge#Aeronautics and astronautics|centrifuges]] used in astronaut training and amusement park rides such as the [[Rotor (ride)|Rotor]], [[Mission: Space]] and the [[Gravitron]] can cause motion sickness in many people.  While the interior of the centrifuge does not appear to move, one will experience a sense of motion.{{dubious|reason= this language confounds both forms of motion and sensations of motion; see talk-page section "confoundings"|date=March 2018}} In addition, [[centrifugal force]] can cause the vestibular system to give one the sense that downward is in the direction away from the center of the centrifuge rather than the true downward direction.<ref>{{Cite journal |last1=Bertolini |first1=Giovanni |last2=Straumann |first2=Dominik |date=2016 |title=Moving in a Moving World: A Review on Vestibular Motion Sickness |journal=Frontiers in Neurology |volume=7 |page=14 |doi=10.3389/fneur.2016.00014 |issn=1664-2295 |pmc=4753518 |pmid=26913019|doi-access=free }}</ref>
