Cells with possible dual projections to both spinal trigeminal nuclei were identified in the rat brainstem following separate injections of different retrogradely transported markers into the right and left spinal trigeminal nucleus. The greatest number of double-labeled cells was located in the nucleus reticularis gigantocellularis. Several double-marked cells were also observed in the nucleus raphe magnus, the nucleus paragigantocellularis and the periaqueductal gray. These results suggest that some cells in the above brainstem nuclei may have a bilateral modulating effect on the spinal trigeminal nuclei.
在大鼠脑干中，通过分别向右侧和左侧三叉神经脊束核注射不同的逆行转运标记物，鉴定出可能向双侧三叉神经脊束核发出双重投射的细胞。双标记细胞数量最多的位于巨细胞网状核。在中缝大核、旁巨细胞网状核和导水管周围灰质中也观察到了一些双标记细胞。这些结果表明，上述脑干核中的一些细胞可能对三叉神经脊束核具有双侧调节作用。
