The expiration reflex in man.
After anaesthetizing the oral, pharyngeal and epiglottal mucosa, the authors stimulated the vocal folds mechanically with a nylon fibre, by means of indirect laryngoscopy, in 58 human subjects. They found that stimulation of the vocal folds also produced in man the same typical expiratory reaction, not preceded by inspiration, which they previously observed in experimental animals.
