The purpose of this morphological study was to investigate the relationship to facial nerve and LI4 related to the large intestine meridian. The common locations of the spinal cord and brain projecting to the LI4 and facial nerve were observed fallowing injection of transsynaptic neurotropic virus, pseudorabis virus(PRV), into the LI4 and facial nerve of the rat. After survival times of 96 hours following injection of PRV, the rats were perfused, and their spinal cord and brain were frozen sectioned(30${\mu}m$). These sections were stained by PRV immunohistochemical staining method, and observed with light microscope The results were as follows: 1. The PRV labeled spinal cord segments projecting to the LI4 and facial nerve were founded in cervical, thoracic, lumbar and sacral segments. Dense labeled areas of each spinal cord segment were founded in lamina IV, V, X, lateral spinal nucleus, intermediolateral nucleus and dorsal nucleus. 2. The PRV labeled medulla oblongata projecting to the LI4 and facial nerve were founded in the A1 noradrenalin cells/C1 adrenalin cells/caudoventrolateral reticular nucleus, rostroventrolateral reticular nucleus, medullary reticular nucleus, nucleus tractus solitarius, raphe obscurus nucleus, raphe pallidus nucleus, raphe magnus nucleus, gigantocellular nucleus, lateral paragigantocellular nucleus, and spinal trigeminal nucleus.
