q2 i? Contrary to prior reports that full cue-feedback pairs can block reactivation, this study found enhanced neural responses to the second word, particularly for difficult items. → Shin 2025

q2 · i? · causal · r2

Authors' interpretation from ERP and TFR analyses showing enhanced responses following the second word of each cue pair, suggesting the second word functioned as a reinstatement signal; each pair was delivered with approximately 5 s spacing during stable NREM sleep.

"the effectiveness of full-pair cues may depend on temporal precision, memory strength, and sleep-stage alignment, and that under optimal con ditions, full cues can successfully promote memory consolidation."

• TMR enhances declarative memory after one night of sleep across paradigms, though some recent studies did not replicate the effect — related
• TMR benefits on name recall are negatively correlated with post-cue sleep disruption and post-cue beta-band EEG power, suggesting reactivation depends on undisturbed sleep — related
• Auditory cueing during NREM sleep elevates slow wave and spindle power relative to no stimulation, with effects concentrated in frontal and central regions — related
• Closed-loop TMR timed to the slow-oscillation up-state improves memory consolidation relative to down-state cueing, though direct up-vs-down comparisons yield mixed results — related
• Personalized TMR improves recall accuracy for the most challenging (L3) word pairs, outperforming both uniform TMR and no-stimulation control in the post-sleep session — related
• Hippocampal sharp-wave ripples during SWS and waking support memory consolidation and spatial task performance — related
