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.
