We separately decreased the conductance of each excitatory synapse to examine how these changes would affect the respiratory pattern. WebThe DRG helps maintain a constant breathing rhythm by stimulating the muscles of inspiration to contract at regular intervals after a passive exhalation. The DRG is not active during passive exhalation. A normal and regular stimulating signal to inspiratory muscles will create a breathing rate that falls somewhere between 12-15 breaths/minute.
