Which pontine centre inhibits the dorsal respiratory group and so controls the overall rate of breathing?

1. The pontine respiratory group consists of the apneustic and pneumotaxic centres. 2. The pneumotaxic centre is a network of neurons that inhibits activity in the dorsal respiratory group. 3. That inhibition allows relaxation after inspiration and so controls the overall rate. 4. The apneustic centre does the opposite: it stimulates the dorsal respiratory group. 5. So the first option is correct and the second is the mirror-image trap. 6. The two respiratory groups named in the third and fourth options lie in the medulla, not the pons. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 22 "The Respiratory System", section 22.3 The Process of Breathing_
