✦ Synopsis
A study was made of the efferent fiber connections of the trigeminal nucleus caudalis in the marmoset monkey (Oedipomidas oedipus). Degeneration resulting from nucleus caudalis lesions in twelve animals was studied by the Nauta technique. Following lesions of the trigeminal nucleus caudalis, degeneration was present bilaterally in the medial reticular formation, medial and spinal lemnisci, ventral horn and nucleus cuneatus. Ipsilateral preterminal degeneration was observed in the intermediate, hypoglossal, supraspinal and retroambigualis nuclei, the trigeminal interpolaris, oralis and main sensory nuclei, and motor nuclei of V and VII cranial nerves. An ipsilateral intranuclear trigeminal path is described. Nucleus caudalis efferent connections with the thalamus are discussed.
