Abstract
The responses of 129 bulbospinal (BS) neurons were investigated an anesthetized cats during the expiration reflex evoked by mechanical stimulation of the vocal folds or electrostimulation of the superior laryngeal nerve. It was found that in addition to expiratory and inspiratory neurons, a large number of nonrespiratory BS cells localized bilaterially, primarily in the giant-cell tegmental fields, are activated. It is shown that expulsive expiration during this reflex is to a considerable extent provided by activation of non-respiratory BS neurons participating also in the transmission of descending influences from high-threshold afferents of other modalities.
