[Preliminary results on the splanchnico-laryngeal reflex in the cat]

Electrical stimulation of low threshold splanchnic afferent nerves in lightly anesthetized cat results in phrenic and recurrent laryngeal nerve responses. Both phrenic and recurrent laryngeal inspiratory nerve activities are inhibited, whereas expiratory recurrent nerve activity is triggered and even increased. The significance of this reflex is discussed in relation to laryngeal adductor muscle contractions and the abdominal pressure increase.
