Up to now, the standardised motion sickness index has been mainly developed for shipping and only takes into account the vertical motion experienced by passengers. This index did not correlate with motion sickness incidence during two field tests realised in tilting trains conducted during 1998 and 2000. Therefore, a railway motion sickness index is required to predict the lack of comfort likel...

This study investigates motion-sickness-related brain responses using a VR-based driving simulator on a motion platform with six degrees of freedom, which provides both visual and vestibular stimulations to induce motion sickness in a manner that is close to that in daily life. Subjects' brain dynamics associated with motion sickness were measured using a 32-channel EEG system. Their degree of ...

This study examined the effect of passengers' active head-tilt and eyes-open/eyes-closed conditions on the severity of motion sickness in the lateral acceleration environment of cars. In the centrifugal head-tilt condition, participants intentionally tilted their heads towards the centrifugal force, whereas in the centripetal head-tilt condition, the participants tilted their heads against the ...

BACKGROUND Both motion sickness and the illusion of self-motion (i.e., vection) can be induced by moving visual scenes. The results of a previous study imply that motion sickness is primarily dependent on visual motion in foveal vision while vection is primarily dependent on motion in peripheral vision. HYPOTHESIS It was hypothesized that similar motion sickness would be produced when trackin...

UNLABELLED Motion sickness presents a challenge due to its high incidence and unknown pathogenesis although it is a known fact that a functioning vestibular system is essential for the perception of motion sickness. Recent studies show that the efferent vestibular neurons contain calcitonin gene-related peptide (CGRP). It is a possibility that the CGRP immunoreactivity (CGRPi) fibers of the eff...

Your brain gets information from several sources concerning the type and direction of your movements. The first, and most important, source is the inner ear. The inner ear, also responsible for balance, contains fluid that shifts according to your body's movement, pushing little hairs one way or the other. This lets your brain know about the direction you're moving in. Your brain also receives ...

INTRODUCTION Severe motion sickness is easily identifiable with sufferers showing obvious behavioral signs, including emesis (vomiting). Mild motion sickness and sopite syndrome lack such clear and objective behavioral markers. We postulate that yawning may have the potential to be used in operational settings as such a marker. This study assesses the utility of yawning as a behavioral marker f...
