Abstract

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 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.
