In anesthetized rats, vagal afferent activities activate slow central mechanisms which modulate the pattern of breathing over several breaths, giving rise to increased breath to breath variability of respiratory pattern. We hypothesized that variability in breathing pattern would produce variability in blood gases and further enhance breath to breath variability of inspired ventilation. Anesthetized rats were placed in a head-out plethysmograph and spontaneous breathing recorded during… CONTINUE READING
