What was done
This narrative review summarizes noninvasive brain stimulation modalities—specifically transcranial electrical, transcranial magnetic, and acoustic stimulation—along with targeted memory reactivation during sleep, focusing on their mechanisms for modulating slow oscillations, sleep spindles, and hippocampal sharp wave ripples to support memory consolidation.
What was found
The abstract reports no quantitative results, sample sizes, or effect sizes. It qualitatively describes that stimulation techniques can enhance slow oscillations and sleep spindles, and that targeted memory reactivation may enhance or stabilize memory consolidation.
Why it matters
The review synthesizes electrophysiological targets for non-pharmacological sleep enhancement aimed at improving cognitive outcomes across healthy and clinical populations.
Limits
As a narrative review, it presents no primary data or systematic pooling. The abstract notes technical considerations for each modality that constrain broader clinical translation, and provides no specific efficacy or safety parameters.
