摘　　要：将荧光金注入单侧大鼠延髓网状背侧亚核进行该部位的传入投射研究。结果发现：在脊髓后角Ⅰ层、Ⅲ～Ⅳ层、Ⅹ层背侧有阳性标记细胞；中缝大核、线性核、中缝背核、中脑导水管周围灰质、丘脑室旁核等均有较多的标记细胞。表明延髓网状背侧亚核与内源性镇痛系统和脊髓之间有广泛的联系，提示该核与痛觉调节活动有关。Fluorogold was injected into the subnucleus reticularis dorsalis(SRD) of the rat to study the afferent its projections. It was found that there are fibers from many parts projecting to SRD,such as:the spinal cord(laminas Ⅰ、Ⅲ～Ⅳ、Ⅹ)、raphe magnus nu,、dorsal raphe nu.、linear raphe nu.、raphe obscurus nu.、the perizaqueductal gray and paraventricular thalamic nu..This study suggests that SRD has extensive communications with endogeneous analgesia system and the spinal cord.It indicates that SRD is involved in nociceptive regulation.
