A marginally significant interaction between CtDCS condition and emotion was indeed found ( F 4,56 = 2.47, p = 0.06, η p 2 = 0.15).

In the theta stimulation condition, the association between theta power during REM sleep and the AoL after sleep showed a trend ( r = 0.46, p = 0.09).

a positive trendno p-value reported

This suggest 5 Hz tDCS could also have been beneficial, in the sense that theta-rich REM sleep can improve implicit procedural memories [ 84 ], and indeed a positive trend was seen between theta power during REM sleep and the AoL after sleep, but no overall benefit to performance was seen.
