连续切片的透射电子显微镜分析表明，受体细胞只受一个神经元支配，而不是以前认为的两个。神经元的两个树突构成神经元胞体所在的尾神经节的传入感觉神经。它的神经突被追踪了几微米，但突触末梢没有被识别出来。Torrence和Cloney将Oikopleuris的这种感觉系统与Diplosoma macdonaldi蝌蚪幼虫的类似尾感觉系统进行了比较。“接线图”提出了两个系统。接受传入感觉神经元的神经节，讨论了进一步研究简单的集成系统的模型。
Transmission electron microscopic analysis of serial sections showed that the receptor cells are innervated by only one neuron and not two as previously believed. The neuron's two dendrites constitute the afferent sensory nerves to the caudal ganglion where the neuron's cell body is located. Its neurite was traced a few micrometers, but the synaptic terminals were not identified. This sensory system inOikopleurais compared with a similar caudal sensory system in the tadpole larva ofDiplosoma macdonaldiinvestigated by Torrence and Cloney. ‘Wiring diagrams’ are proposed for the two systems. The ganglia, which receive the afferent sensory neurons, are discussed in terms of models for further research on simple integration systems.
