Some Current Topics of Interest in the Physiology of Trigeminal Pain: A Review 1

There are many similarities between the trigeminal system and the spinal cord with respect to the peripheral and central nervous mechanisms underlying the sensation of pain. There are several recent reviews which give excellent accounts of what is known about the neural mechanisms involved in pain (e.g. Zimmermann 1979, Dubner et al. 1978), but this paper is restricted to discussing some aspects of trigeminal pain mechanisms which are of particular current interest.
