The innervation of the phrenic motor nucleus in the cat by serotonin-containing neurons has been studied using retrograde tracing combined with immunohistochemistry at the electron microscope level. It was found that phrenic motoneuron cell bodies and dendrites are contacted by serotonin-immunoreactive synaptic terminals. This finding suggests that the activity of phrenic motoneurons is directly affected by serotonergic neurons.
利用逆行追踪结合电子显微镜水平的免疫组织化学技术，对猫膈运动核中含5-羟色胺的神经元的神经支配进行了研究。结果发现，膈运动神经元的胞体和树突与5-羟色胺免疫反应性突触终末相接触。这一发现表明，膈运动神经元的活动直接受到5-羟色胺能神经元的影响。
