<P> The pneumotaxic center, also known as the pontine respiratory group (PRG), is a network of neurons in the rostral dorsal lateral pons . It consists of the subparabrachial nucleus and the medial parabrachial nucleus . It is considered an antagonist to the apneustic center, which produces abnormal breathing during inhalation . It limits inspiration . </P> <P> The PRG antagonizes the apneustic center, cyclically inhibiting inhalation . The PRG limits the burst of action potentials in the phrenic nerve, effectively decreasing the tidal volume and regulating the respiratory rate . Absence of the PRG results in an increase in depth of respiration and a decrease in respiratory rate . </P>
