Subclaims¶

q2 i? SWRs during SWS reactivate hippocampal and cortical activity patterns from past experiences and are thought to play an important role in memory consolidation. → Drew B. Headley and Denis Paré 2017 q2 i? Disrupting awake SWRs impairs performance on a spatial working memory task. → Drew B. Headley and Denis Paré 2017 (2)

q2 · i? · review · r3

The review reports that SWS SWRs occur at cortical upstate onset and reactivate prior experience patterns, with cortical and striatal replay events partly initiated by SWRs. The role is characterized as supported by multiple converging lines of evidence.

"SWRs tend to occur at the onset of upstates, 27,33,34 and are thought to play an important role in memory consolidation by reactivating hippocampal and cortical activity patterns that occurred during past experiences."

q2 · i? · review · r2

The review cites rodent experiments in which "Disrupting these online SWRs impairs performance on a task requiring spatial working memory", providing interventional support for awake-SWR replay's behavioral role during consummatory pauses.

"Disrupting these online SWRs impairs performance on a task requiring spatial working memory (Fig. 2).39"

• REM theta supports consolidation of select procedural memories such as emotional memory, but not skilled motor memory — related
• Cortical delta oscillations during slow-wave sleep support declarative memory consolidation — 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
• 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
• TMR efficacy depends on memory strength and task difficulty: benefits concentrate on moderately strong and challenging items, with limited advantage for easy (L1) items — related
• Multivariate classification of SW power, spindle power, and SW-spindle coupling distinguishes the personalized TMR, TMR, and control groups above chance, peaking around 3 s after cue onset — related
• Full word-pair cues can promote rather than disrupt reactivation when delivered with sufficient spacing and during stable NREM sleep — related
• In the personalized TMR group, memory improvement for challenging items correlates positively with SW-spindle coupling (r = 0.70), but no such correlation appears in the All condition or other groups — related
