    ..e., confinement in a locked wheel). These results suggest that not only LiCl but also running induces nausea in rats, supporting the gastrointestinal discomfort hypothesis of running-based taste aversion learning. ..

    ..This US crossover effect suggests the possibility that wheel running and LiCl injection share a common or similar physiological mechanism in inducing taste aversion. ..
  4. Nakajima S. Swimming-based pica in rats. Behav Processes. 2016;130:1-3 pubmed publisher
    ..Because kaolin intake has been regarded as a measure of nausea in rats, this finding suggests that swimming activity, as well as voluntary or forced running, induces nausea in rats. ..

    ..This finding is congruent with the contention that consumption of kaolin clay is not only a useful index of, but also an effective remedy for, drug-induced nausea in rats. ..
  6. Nakajima S. Running induces nausea in rats: Kaolin intake generated by voluntary and forced wheel running. Appetite. 2016;105:85-94 pubmed publisher
    ..Because kaolin intake is regarded as a reliable measure of nausea in rats, these results show that wheel running, either voluntary or forced, induces nausea in rats. ..

    ..These results, when taken together, support the hypothesis that pica behavior generated by wheel running reflects nausea in rats. ..
