Integrated peak EMG activity of different respiratory muscles across brain-state transitions in urethane-anesthetized rats

	REM-like	Transition	nREM-like
Peak ∫DIA_EMG	0.99 ± 0.23 (0.56)	0.97 ± 0.22^* (0.007)	1 ± 0.23
Peak ∫INT_EMG	0.98 ± 0.31 (0.3)	0.97 ± 0.28 (0.09)	1 ± 0.29
Peak ∫GG_EMG	0.74 ± 0.22^* (0.03)	0.70 ± 0.19^* (0.04)	1 ± 0.31
Peak ∫ABD_EMG	1.81 ± 0.62 (0.06)	1.35 ± 0.11^* (0.04)	1 ± 0.23
	2.49 ± 0.94^** (0.048)	1.81 ± 0.64 (0.05)

Averaged integrated peak EMG values for DIA, INT, GG, ABD, and LL muscles for the REM-like, transition, and nREM-like states in urethane-anesthetized rats. Values were normalized to the averaged EMG peak value obtained during nREM-like state. Values in parentheses are p values for comparison between nREM-like state and REM-like or transition states.

*p < 0.05, statistical significance of states (REM-like or transition) relative to nREM-like epochs.

**p < 0.05, statistical significance of changes during plateau period of abdominal activation in REM-like relative to nREM-like epochs.
