“…The splint, which provided a means of delivering air-pulse trains to the peritonsillar region, was made of human-implant-grade silicone that was molded over a dental impression cast (Apollo Microsurgicals, London, ON). Because of a potential effect of jaw opening on the threshold for evoked swallowing [31], the splint thickness was designed to fall within the just noticeable difference (JND) for jaw position (i.e., 1-2 mm [32,33]). Polyethylene tubing (inner diameter (ID)-1.14 mm, outer diameter (OD)-1.57 mm) embedded in the silicone ran along the inferior border of the splint lateral to the alveolar ridge of the mandible and extended approximately 1 cm past the posterior edge of the dental splint.…”

This study sought to determine whether air-pulse trains delivered to the peritonsillar area would facilitate swallowing in healthy subjects. Trains of unilateral or bilateral air pulses were delivered to the peritonsillar area via tubing embedded in a dental splint, while swallows were simultaneously identified from their associated laryngeal and respiratory movements. Results from four subjects indicated that oropharyngeal air-pulse stimulation evoked an irrepressible urge to swallow, followed by an overt swallow as verified by laryngeal and respiratory movements. Moreover, air-pulse stimulation was associated with a significant increase in swallowing frequency. Mean latency of swallowing following bilateral stimulation tended to be less than the latency of swallowing following unilateral stimulation. These findings in healthy adults suggest the possibility that oropharyngeal air-pulse stimulation may have clinical utility in dysphagic individuals.

“…It is well known that position sense is important for any organ operating in a spatial context (Broekhuijsen & van Willigen, 1983;McCloskey, 1978). In the absence of the ability to sense the position of a limb, one would lose the control of the limb and would not be able to direct it to perform purposeful motions.…”

“…The transmission of sensory feedback from the masticatory muscles to the cerebral cortex is thought to be important both in the control of orofacial movement and mandibular kinesthesia (Luschei and Goodwin, 1974;Christensen, 1976;Hellsing, 1977;Morimoto et al, 1981;Broekhuijsen and Van Willigen, 1983;Morimoto, 1983Morimoto, , 1990Enomoto et al, 1987). Despite the significance of these functions, little is known about the neuronal circuits and synaptic mechanisms involved in these processes.…”

Trigeminothalamic neurons were retrogradely labeled by injection of horseradish peroxidase into the ventroposteromedial nucleus of the thalamus in rats. Jaw-muscle spindle afferent axons were then physiologically identified and intracellularly stained with biotinamide. The ultrastructure of labeled spindle afferent boutons was then studied in the caudolateral supratrigeminal region (Vsup) and dorsomedial trigeminal principal sensory nucleus (Vpdm). A total of 418 stained spindle afferent boutons were identified in Vsup and Vpdm; approximately 75% of these synapsed with dendrites, 10% synapsed with somata, and 15% synapsed with axons. Most jaw-muscle spindle afferent boutons were postsynaptic to unlabeled P-type boutons. Reciprocal synapses between spindle afferent boutons and unlabeled boutons were occasionally observed. A few dendrites in Vsup and Vpdm received synapses from multiple spindle afferent boutons. Conversely, some large (from 3 x 6 to 4 x 8 microns) and giant (from > 4 x 8 to 5 x 10 microns) spindle afferent boutons simultaneously contacted two to five dendrites and/or somata. Jaw-muscle spindle afferent boutons also formed synapses with retrogradely labeled trigeminothalamic neurons in Vsup and Vpdm. Numerous unlabeled S-and F-type boutons converged onto the same trigeminothalamic dendrite or soma contacted by a spindle afferent bouton. A small number of synaptic triads consisting of an unlabeled P-type bouton, a spindle afferent bouton, and either a dendrite or soma were also encountered. These data indicate that sensory feedback from the masticatory muscles is subject to presynaptic inhibition and integration prior to reaching the thalamus. This pathway is likely to be important in the relay of proprioceptive and kinesthetic information from the muscles of mastication to the thalamus.
