Local unilateral perfusion of high K+ to the PBC bilaterally increases inspiratory burst frequency but not peak integrated activity or inspiratory burst duration. A. Representive raw (XII) and rectified and integrated (∫XII) hypoglossal rootlet recordings from the ipsilateral (Ipsi) and contralateral (Contra) hypoglossal rootlets in the control condition and following local unilateral perfusion of high K+ (80 mM). A and B. Local perfusion of high K+ to the unilateral PBC bilaterally increases inspiratory burst frequency. C and D. Unilateral excitation of PBC did not significantly affect peak integrated activity or inspiratory burst duration bilaterally. **P < 0.01; paired t-test v.s. control
