描述了斑马鱼幼鱼中一类网状神经元，根据其轴突的分支模式命名为T中间神经元。通过用CNS内应用部位的HRP [辣根过氧化物酶]填充细胞来鉴定细胞。一组连续重复的. apprx。10个这样的神经元存在于尾侧后脑两侧的纵列中。T轴突穿过中线投射，分支在内侧纵束（MLF）内向吻侧和尾侧行进。这些细胞接受来自Mauthner神经元的突触输入，来自mlf中未识别的轴突，可能来自三叉神经感觉纤维。它们投射到颅和胸运动核。T中间神经元似乎是同源的巨纤维神经元的hatchetfish和一些颅中继神经元的金鱼。一个可能的功能作用和比较的影响，它们在后脑的分布进行了讨论。
A class of reticular neurons, named T interneurons after the branching pattern of their axons, in young larvae of the zebrafish Brachydanio rerio is described. The cells were identified by filling them with HRP [horseradish peroxidase] from application sites within the CNS. A serially repeating set of .apprx. 10 such neurons is present in a longitudinal column on each side of the caudal hindbrain. The T axons project across the midline, and branches course both rostrally and caudally within the medial longitudinal fascicle (mlf). The cells receive synaptic input from the Mauthner neurons, from unidentified axons in the mlf and perhaps from trigeminal sensory fibers. They project to cranial and pectoral motor nuclei. T interneurons appear to be homologous to giant fiber neurons in the hatchetfish and to some of the cranial relay neurons in the goldfish. A possible functional role and comparative implications of their distribution in the hindbrain are discussed.
