The results showed that the largeamounts of degenerative fibers could be found bilaterally in trigeminal spinal nucleus and its tract,trigeminal principal sensory nucleus, trigeminal mesencephalic nucleus and some degenerations couldbe observed ipsilaterally in solitary tract and its nucleus, medullary lateral reticular nucleus, giganto-cellular reticular nucleus and nucleus raphe magnus following transection of infraorbital nerve. A verymoderate degenerative fibers could be identifed in ipsilateral accessory spinal nucleus and spinal reticu-lar nucleus. A few degenerative fibers were seen on the contralateral magnocellular part of caudatepart of trigeminal spinal nucleus by passing through the posterior commissure of canalis centralis.These results suggest that the primary information of acupoints of Quanliao and Shibai could be trans-mittered into the above展开更多
