关于中缝背核(dorsal raphe nucleus.DR)5—HT能神经元的轴突投射研究较多,但对其树突的分支、分布报道较少。作者用神经生物学领域内较先进的研究手段——细胞内HRP注射法,对DR内单个5—HT能神经元树突的形态结构进行了较详细地观察,
There are many studies on axon projection of 5-HT neurons in dorsal raphe nucleus (DR), but there are few reports on the distribution and branching of dendrites. The authors use the more advanced research methods in the field of neurobiology - intracellular HRP injection method to observe the morphological structure of single 5-HT neuron dendrites in DR in more detail,
