Corticifugal Pathways for Mastication, Lapping and Other Motor Functions in the Cat

Role of the Pontine Reticular Formation in the Neural Organization of Deglutition

“…In addition to these, widespread areas in the midbrain reticular formation exert an inhibition (SUMI, 1971), whereas, as the present study disclosed, a narrowly restricted area of reticular formation in the pons yields both excitation and inhibition of swallowing elicited either peripherally or centrally. It is conceivable that the pontine reticular formation may modify swallowing activity in a way analogous to the reticular activating and inhibiting system found first by MAGOUN (1952MAGOUN ( , 1965 and MoRUZZI (1960). Such action of the midbrain reticular formation has recently been proposed to be the case in rhythmic chewing (SUMI, 1971).…”

Evidence for central timing of rhythmical mastication

“…It appears that, as originally postulated by Magoun et al (1933), mastication is patterned within the central nervous system. There is also ample evidence that this patterning occurs within the brain stem (Bremer, 1923;Magoun et al 1933;Lund & Dellow, 1970) and is activated by higher centres or from the oral cavity.…”

Bremer (1923) observed rhythmical mastication in chronically decerebrate rabbits in response to oral stimuli, while Monnier & Willi (1947) found that human medullo-spinal anencephalics could carry out the closely related activity of rhythmical sucking.…”

Neural Descending Pathways From the Cortical Jaw Motor Area and Amygdaloid Nucleus to Jaw Muscles

“…The descending pathway from the cortex for mastication has been studied by many workers3, 8,9,10,11). This pathway for mastication was first traced through the internal capsule by Rime) in the rabbit.…”
