A new form of taste aversion conditioning was established in the pond snail Lymnaea stagnalis. An associative memory, lasting 24h, was produced in the pond snail with 20 pairings of 100 mM sucrose as the conditioned stimulus (CS) and mechanical stimulation to the head as the unconditioned stimulus (UCS). Animals exposed to reverse pairings of the CS and UCS failed to learn the association. The learning was characterized by a shift in the response to the UCS from a whole-body withdrawal response to the cessation of feeding behavior.
在椎实螺（Lymnaea stagnalis）中建立了一种新的味觉厌恶条件反射形式。通过将100 mM蔗糖作为条件刺激（CS）与头部机械刺激作为非条件刺激（UCS）进行20次配对，在椎实螺中产生了持续24小时的联想记忆。暴露于CS和UCS反向配对的动物未能学会这种关联。这种学习的特征是对UCS的反应从全身退缩反应转变为进食行为的停止。
