The morphological basis of long-term sensitization of the gill-and-siphon withdrawal reflex in Aplysia was explored by examining the structure of identified sensory neuron synapses in control and behaviorally modified animals. Following long-term training, sensitized animals displayed an increase in the number of sensory neuron synapses compared to control animals. The relative permanence of these structural changes and their similarity in time course to the behavioral duration of sensitization suggest a role for synapse number changes during long-term memory.
通过检查对照动物和经过行为修饰的动物中已识别的感觉神经元突触结构，探索了海兔鳃和虹吸管退缩反射长期敏感化的形态学基础。经过长期训练后，与对照动物相比，敏感化动物的感觉神经元突触数量增加。这些结构变化的相对持久性及其在时间进程上与敏感化行为持续时间的相似性表明，突触数量变化在长期记忆中发挥了作用。
