The apneustic centre of the lower pons appears to promote inhalation by constant stimulation of the neurons in the medulla oblongata.

Where is the Apneustic area located?

The apneustic center, which is located in the lower pons, is thought to excite the inspiratory center. Rather than abruptly sending signals to the inspiratory muscles to contract, stimulation of the apneustic center leads to a gradual increase in the firing rate of the inspiratory muscles.

What is the function of apneustic center?

The apneustic center sends signals for inspiration for long and deep breaths. It controls the intensity of breathing and is inhibited by the stretch receptors of the pulmonary muscles at maximum depth of inspiration, or by signals from the pnuemotaxic center. It increases tidal volume.
