In one paragraph
Pooling 31 studies that measured sleep spindles alongside learning, the authors find that spindle density during the night predicts next-day recall. The link is strongest for word pairs learned shortly before sleep and weaker, and less consistent, for procedural tasks.
Contributions
A pooled effect of spindle density on overnight recall across 31 studies and 1,140 participants.
A moderator analysis separating declarative from procedural tasks.
