Fig. 4: The interactive functional roles of SWS and REM sleep in memory representational transformation.
From: Slow-wave sleep and REM sleep differentially contribute to memory representational transformation
A and B SWS*REM showed no significant correlation with either item-level or category-level representational strength change (Post minus Pre). C and D REM/SWS was negatively associated with item-level representational strength change. E and F REM/SWS was positively correlated with category-level representational strength change. Significant clusters with pcluster < 0.05 were circled by black lines. Z(ρ): Fisher Z-transformed Spearman’s correlation coefficient; *p < 0.05; **p < 0.01; ***p < 0.001.
