Pneumotaxic center; True is:

Pneumotaxic Center : Controls rate of breathing. Located in the medial parabrachial and Kolliker-Fuse nuclei of the dorsolateral pons. Contains both I and E neurons. The normal function of the pneumotaxic center is unknown, but it may play a role in smooth switching between inspiration and expiration (“fine-tune” of the breathing). A strong pneumotaxic signal can increase the rate of breathing 30-40 breaths per minute, whereas a weak pneumotaxic signal may reduce the rate to only 3-5 breaths per minute.
