Abstract:
The efferent projections to the spinal cord from the brain stem were studied with HRP. Fifty per cent solution of HRP was slowly injected into the intumescentia cervicalis at six points on its right side in 10 albino rats and the HRP-labelled cells were found in the following nuclei:1. Of the midbrain: the nucleus linearis, nucleus raphe dorsalis, substantia nigra, nucleus ruber, nucleus cuneiformis, nucleus colliculus superior, nucleus Edinger-Westphal, nucleus Darkschewitsch, nucleus interstitialis (Cajal), nucleus ventralis tegmenti and nucleus dorsalis tegmentalis;2. Of the ports: the nucleus raphe magnus, nucleus medianus raphe, nucleus trigemini principalis, nucleus lemnisci lateralis, nucleus reticularis pontis oralis, nucleus reticularis pontis caudalis, locus ceruleus, nucleus subceruleus, nucleus vestibularis lateralis, nucleus vestibularis medialis, nucleus parabrachialis and nucleus olivaris su- perior;3. Of the medulla oblongata: the nucleus raphe obscurus, nucleus raphe pallidus, nucleus gracilis, nucleus cuneatus, nucleus tractus spinalis nervi trigemini, nucleus tractus solitarius, nucleus commissuralis (Cajal), nucleus reticularis lateralis, nucleus reticularis paramedianus, nucleus reticularis gigantocellularis and nucleus olivaris inferior;4. Of the cerebellum: the nucleus medialis and lateralis.The functions of spinal projection from the nuclei raphe, reticularis, locus ceruleus, substantia nigra and the nucleus dorsalis tegmentalis have been discussed.
