Observational study of effects of pharyngeal stimulation by carbonated solution on repetitive voluntary swallowing in humans
In this study, we conducted observational study to examine the effects of pharyngeal stimulation by a bolus of carbonated solution on repetitive voluntary swallowing in humans. Twelve healthy participants had a fine silicone tube inserted into their pharyngeal region, through which various solutions...
