Abstract

Although it is well known that periodontal afferent excitation evokes jaw-closing and jaw-opening reflexes, details of the neuronal circuits related to these reflexes are incomplete. We have therefore carried out a series of morphological and physiological investigations of 43 periodontal mesencephalic (Vmes) afferents. At the same time we have gathered data on 102 jaw-closing and jaw-opening motoneurones, 13 jaw-closing muscle spindle afferents and 14 premotor interneurones in trigeminal subnucleus oralis (Vor).
