A combination of optical and electrode recording methods was used to obtain an overview of the neuron activity in the Aplysia abdominal ganglion in response to a light touch to the siphon skin. Spike activity was detected in up to 150 different neurons. Habituation and sensitization of the gill-withdrawal reflex was accompanied by large changes in the number of activated neurons. It is likely that these recordings are incomplete; the actual number of activated neurons is estimated to be about 300 in the acutely sensitized preparation. While we presume that not all 300 of these neurons are involved in the gill-withdrawal reflex, the number of neurons is so large that it may be difficult to determine the role of each activated neuron with presently available experimental tools.
采用光学和电极记录方法相结合的方式，以获取海兔腹神经节中神经元活动的概况，该活动是对虹吸管皮肤的轻触所做出的反应。在多达150个不同的神经元中检测到了峰电位活动。鳃收缩反射的习惯化和敏感化伴随着激活神经元数量的巨大变化。这些记录可能并不完整；在急性敏感化标本中，激活神经元的实际数量估计约为300个。虽然我们推测并非所有这300个神经元都参与鳃收缩反射，但神经元数量如此之多，以至于用目前可用的实验工具可能很难确定每个激活神经元的作用。
