Otolith signal processing and motion sickness
conference paper
According to the widely accepted sensory conflict theory, motion sickness arises in situations in which "the motion signals transmitted by the eyes, the vestibular system, and the non-vestibular proprioceptors are at variance either with one another or with what is expected from previous experience." Consequently, several types of sensory conflict have been defined. We suggest a simpler theory, which only requires one conflict to sufficiently explain all types of motion sickness. This can be summarized by the definition: "All situations which provoke motion sickness can be characterized by a condition in which the subjective vertical as determined on the basis of the integrated information from the eyes, the vestibular system, and the non-vestibular proprioceptors, is at variance with the expected vertical from previous experience." We are implementing a mathematical model of this so-called Subjective Vertical Conflict theory, which successfully predicts empirical data on the motion sickness incidence (MSI) during vertical motion.
De overdrachtsfunctie van de otolieten werd experimenteel vastgesteld en de incidentie van zeeziekte als gevolg van verticale bewegingen succesvol gesimuleerd.
