Studies on exercise-based taste aversion learning

在活动轮中自愿跑步或在水池中强迫游泳使大鼠对运动前立即消耗的味道溶液产生厌恶。由于味觉和运动的相关性是建立味觉厌恶的必要条件，这种现象被认为是一种经典条件反射（或联想学习），味觉作为条件刺激，运动作为非条件刺激。本研究旨在探讨运动性味觉厌恶学习的机制，并通过比较不同品系大鼠的学习成绩来证明运动性味觉厌恶学习的共性。

Voluntary running in an activity wheel or forced swimming in a water pool endows rats with aversion to the taste solution consumed immediately prior to the exercise. Because the correlation of taste and exercise is necessary to establish taste aversion, this phenomenon has been considered to be a type of classical conditioning(or associative learning), with the taste as a conditioned stimulus and the exercise as an unconditioned stimulus. The present research investigated the underlying mechanism of exercise-based taste aversion learning and demonstrated its generality by comparing performance of different strains of rats.
