Closed-loop stimulation may improve memory through more than just boosting slow waves. Grimaldi et al. found that better retention tracked the balance of slow-oscillation vs delta coupling to spindles, along with ⬆️ parasympathetic activity—not simply stronger SO–spindle coupling.

Acoustic enhancement of slow wave sleep improves memory retention by coordinating brain oscillatory rhythms and autonomic activity
Sleep plays a crucial role in memory consolidation. While the interaction between sleep oscillations and autonomic activity likely influences this process,
