title: Ascending and cerebellar non-serotonergic projections from the nucleus raphe magnus of the rat.
abstract: Non-serotonergic ascending and cerebellar projections of rat nucleus raphe magnus (RM) were disclosed using the horseradish peroxidase technique. The ascending bundle rose form rostral RM and was divided into two components; one ascended in raphe regions and the other in reticular formation. The former on innervated n. raphe dorsalis, etc., and the latter n. parafascicularis, zona incerta, etc. On the other hand, the axons innervating neocerebellum originated exclusively from caudal RM.
