[Functional differentiation of afferents of the superior laryngeal nerve in the cat].
Excitability of the electrically stimulated superior laryngeal nerve afferents and reflex discharges in the respiratory motor nerves were studied on cats under light nembutal anesthesia. Three types of group A afferent fibres were differentiated according to their functional role in reflex response initiation. Low-threshold afferent fibres (A beta) are concerned with proprioceptive activation of laryngeal muscles, the group of A gamma afferents participates in regulation of the respiratory phase-switching mechanisms and high-threshold afferent fibres (A delta) support protective respiratory reflexes.
