Input-output relationships of central neural circuits involved in respiration in cats

摘要

1. Inspiratory output responses, measured as integrated phrenic activity, to hypercapnia, to unilateral and bilateral carotid sinus nerve stimulation and to combinations of these stimuli were determined in paralysed, vagotomized and glomectomized cats whose end-tidal PCO2 was kept constant by means of a servo-controlled ventilator. In addition, the effect on these responses of the mechanism that causes the respiratory after-discharge was determined.
