Motion sickness in mice and conditioned taste aversion.

Forty-eight male mice in 6 groups were studied. Conditioned taste aversion (CTA) in mice was produced by various motions including cross-coupled acceleration, rotation to two directions (with or without visual field) and linear acceleration. Deprived of water for 24 hours, the mice were exposed to motion immediately after drinking a novel solution, 0.15% saccharin. All groups received two pairings of CTA training related to motion. The results showed that both of cross-coupled and rotation produced frank CTA and former was far more obvious than the latter. In addition, motion with visual field had a trend to intensify sickness response.
