Data are the mean (SEM) for power within distinct EEG frequency bands, slow oscillation, and spindle parameters. Right columns indicate correlations with the PatSep retention score and respective p values.
↵^aCorrelations for frequency bands that were not normally distributed were calculated with Spearman's ρ, all others with Pearson product–moment correlation.
↵*p < 0.05.
