Fig. 5: The relationship between sleep EEG power and memory representational strength change.
From: Slow-wave sleep and REM sleep differentially contribute to memory representational transformation
A and B Total frontal theta (4–7 Hz) power during REM sleep was negatively associated with the item-level strength change (post- minus pre-sleep) and positively associated with the category-level strength change (post- minus pre-sleep). C and D Total frontal beta (15–25 Hz) power during REM sleep was negatively associated with the item-level strength change, and a positive but nonsignificant trend was found between the beta power and category-level strength change. E and F Total frontocentral SO-related (1–1.25 Hz) power during SWS was negatively correlated with the category-level strength change, but not correlated with the item-level strength change. *pFDR < 0.05.
