Central chemoreceptor drive to breathing was studied in unanesthetized toads, equipped with face masks to measure pulmonary ventilation and arterial catheters to analyze blood gases. Two series of experiments were performed. Expt. 1: The fourth cerebral ventricle was perfused with solutions of mock CSF, adjusted to stepwise decreasing pH values. Concomitant perfusion-induced increases of pulmonary ventilation, pHa and PaO2 were measured. Expt. 2: Inspiration of hypercapnic gas mixtures was… CONTINUE READING
