Oral and facial representation in the trigeminal principal and rostral spinal nuclei of the cat

Abstract: Transganglionic transport of horseradish peroxidase (HRP) was used to study the patterns of termination of somatic afferent fibers innervating oral and facial structures within the principal nucleus (Vp), nucleus oralis (Vo), and nucleus interpolaris (Vi). The primary trigeminal afferent fibers that innervate the oral cavity supplied by the pterygopalatine, superior alveolar, lingual, buccal, and inferior alveolar branches, as well as the facial skin supplied by the frontal, corneal, zygomatic, infraorbital, a… Show more

“…The dorsomedial nucleus, first described by Åstrøm (1953), can be distinguished from the rest of the Vo by its cytoarchitecture and is highly developed in rodents. The nucleus is known to receive trigeminal primary projection from exclusively intraoral structures (Arvidsson and Gobel, 1981;Marfurt, 1981;Jacquin et al, 1983;Marfurt and Turner, 1984;Shigenaga et al, 1986aShigenaga et al, ,b, 1989Takemura et al, 1987Takemura et al, , 1991. Prominent CGRP-and SP-ir projection of exclusively trigeminal primary neurons as shown in this study has added another characteristic that distinguishes the rodent dorsomedial nucleus from the rest of the BSTC.…”

“…Most neurons in these nuclei have trigeminal inputs, and many had small mechanosensitive receptive fields within and around the mouth, as shown in earlier studies of rabbits and other species (Eisenman et al, 1963;Olsson et al, 1986a;Shigenaga et al, 1986;Donga and Lund, 1991).…”

“…27 The dorsomedial part of the Sp5O is a region that receives primary afferents of intra-oral structure, and the neurons in the Sp5O have widely spreading dendrites and axons that project to the Mo5. 7,24 Moreover, the neurons in the Sp5O receiving the periodontal Me5 input are related to the formation of a disynaptic or multisynaptic segmental reflex pathway. 8 The rostro-dorso-medial part of the Sp5O contains interneurons to the jaw closing and opening motor neurons in the Mo5 11 .…”

“…[1][2][3][4][5][6][7][8][9][10][11] Mastication increases neuronal activities in various regions of the cerebral cortex. 12 After tooth loss, the remnants of the periodontal ligaments break down and gradually disappear thus inducing the loss of the periodontal mechanoreceptors (PMRs) in the periodontal ligaments.…”
