After 10-15 food stimuli paired with electrical shock in semi-intact snail preparation, responses to strong tactile stimuli identified feeding behaviour neurones were studied. Inhibition evoked by tactile stimulation in these cells before learning procedure disappeared and in some cases noxious stimulus evoked synaptic activation corresponding to feeding reactions in the intact animal. Changes in second-order sensory neurones pre-synaptic to the command neurones of avoidance behaviour are suggested to be the mechanism of forward conditioned connection as well as the mechanism of backward conditioned connection.
在半完整蜗牛标本中，将10 - 15次食物刺激与电击配对后，研究了对强烈触觉刺激的反应，这些刺激可识别出摄食行为神经元。在学习过程之前，这些细胞中由触觉刺激诱发的抑制消失了，在某些情况下，有害刺激诱发了与完整动物摄食反应相对应的突触激活。有观点认为，与回避行为的指令神经元突触前连接的二阶感觉神经元的变化是前向条件连接的机制，也是反向条件连接的机制。
