Data are expressed as arbitrary units (a.u.) in panel A. The data in panel B are normalized relative to baseline activity (% baseline). In panel C, changes in phrenic burst amplitude are expressed relative to the maximal response recorded during the protocol (% max). *: P < 0.05; **: P < 0.01 compared with the baseline. ##: indicates difference between CL and IL phrenic burst amplitude, P < 0.01.
