What was done
This narrative review summarizes three categories of noninvasive stimulation applied during sleep: direct cortical stimulation using electrical or magnetic fields, sensory stimulation using auditory, olfactory, or vestibular pathways, and autonomic balance modulation aimed at enhancing parasympathetic dominance via heart rhythm synchronization.
What was found
The abstract reports no numerical findings, statistical comparisons, or effect sizes. It qualitatively notes that direct brain stimulation can trigger slow oscillations and sleep spindles, sensory stimulation induces paradigm-dependent sleep-modulating effects, and autonomic stimulation decreases heart rate to modulate sleep homeostasis, collectively reported to enhance slow-wave sleep, consolidate declarative and procedural memory, and alter sleep macrostructure.
Why it matters
This review synthesizes diverse non-pharmacological modalities designed to engineer sleep architecture and enhance cognitive consolidation during sleep. It outlines technical paradigms that could serve as alternatives for treating sleep disruption or optimizing sleep quality.
Limits
The abstract describes a narrative overview rather than a systematic review or meta-analysis. No sample sizes, individual study designs, stimulation parameters, or quantitative effect sizes are provided, and potential risks, adverse effects, or long-term clinical efficacy are not addressed.
