Source δ power [1–4 Hz] first and last cycle REM contrasted with wakefulness

		Peak MNI
Region	p value cluster	X	Y	Z	Z value
First cycle REM > wake
R postcentral gyrus, R precentral gyrus, R SMG, R PCC	p < 0.0001	45	-23	39	4.36
L postcentral gyrus, L precentral gyrus, L PCC	p < 0.0001	-9	-25	44	3.77
R parietal operculum	p = 0.02	45	-21	18	3.67
Last cycle REM > wake
R postcentral gyrus, R precentral gyrus, R SMG, R PCC	p < 0.0001	38	-20	46	3.79
L postcentral gyrus, L precentral gyrus, L SMG, L PCC, L SMC	p < 0.0001	-12	-20	40	3.58
L parietal operculum	p = 0.01	50	-21	19	3.53

All clusters significant at p < 0.05, FDR cluster corrected (height threshold, p < 0.01). SMG = supramarginal gyrus; PCC = posterior cingulate cortex; SMC = supplementary motor cortex.
