Acupuncture Induced Analgesic Effects in Ascending Spinal Cord Pathways of the Rabbit,

Afferent impulse induced by acupuncture are transmitted upwards along the pathway of the lateral funiculi contralaterally. Based on the results of the sections of the dorsal funiculi in three cases, as well as sections of the lateral funiculi at the upper dorsal region in other animals, a strong acupuncture analgesic effect was observed. The ventralateral funiculi are of special importance in acupuncture analgesia trajectory. Furthermore, evidence from recent neuroanatomical studies indicates that the ascending fiber pathway of the anterior lateral funiculi or ventralateral funiculi transmits directly to the reticular formation of the brain stem, the central gray matter, as well as to the intralaminar thalamic nuclei 5-7. Therefore, there must be some interaction between acupuncture and these formations in the analgesic mechanism.
