本文描述并比较了两种两栖动物（爪蟾类和三角鱼类）和两种鱼类（长尾鱼类和短尾鱼类）胚胎和幼体的脊髓神经元。它们可以被归为数量有限的常见神经元类：Rohon-Beard感觉神经元、背外侧和背外侧联合感觉中间神经元、抑制性上升中间神经元、两类抑制性联合中间神经元、兴奋性下降中间神经元、运动神经元和可能的感觉Kolmer-Agdhur神经元。在黑斑鱼和其他尾动物中，也有巨大的背外侧联合感觉中间神经元。脊髓神经元在简单屈曲反应和游泳中的功能主要是根据爪蟾蝌蚪的证据来考虑的。(C) 2001爱思唯尔科学公司
The spinal neurons in the embryos and young larvae of two amphibians (Xenopus and Triturus) and two fish (Oryzias and Brachydanio) are described and compared. They can be placed into a limited number of common neuron classes: Rohon-Beard sensory, dorsolateral and dorsolateral commissural sensory interneurons, inhibitory ascending interneurons, two classes of inhibitory commissural interneuron, excitatory descending interneurons, motoneurons and possible sensory Kolmer-Agdhur neurons. In Triturus and other urodeles, there are also giant dorsolateral commissural sensory interneurons. The functions of the spinal neurons in simple flexion responses and swimming are considered in relation to evidence mainly from the Xenopus tadpole. (C) 2001 Elsevier Science Inc.
