The structure of the synaptic connections between identified sensory and giant command neurons of the parietal ganglia of the snail is examined. It is shown that the excitatory postsynaptic potential arising in the giant neuron in response to the generation of a single action potential in the presynaptic neuron consists of several monosynaptic components and may include polysynaptic components. It is hypothesized that monosynaptic components of the elementary excitatory postsynaptic potential that differ in the duration of the latent period and the dynamics of habituation may be associated with the activation of synaptic buttons on axon terminals of varying length.
研究了蜗牛顶神经节中已识别的感觉神经元和巨大指令神经元之间突触连接的结构。结果表明，突触前神经元产生单个动作电位时，巨大神经元中产生的兴奋性突触后电位由几个单突触成分组成，可能还包括多突触成分。据推测，基本兴奋性突触后电位的单突触成分在潜伏期持续时间和习惯化动态方面存在差异，这可能与不同长度轴突终末上突触小体的激活有关。
