Motor learning promotes regionally-specific spindle-slow wave coupled cerebral memory reactivation

D. Baena, E. Gabitov, et al.

Sleep drives precise memory replay: this study shows that slow wave–spindle (SW‑SP) coupling time‑locks motor memory reactivations specifically to the hemisphere involved in learning, while uncoupled spindles recruit primary sensory areas and may support sleep maintenance. This research was conducted by Daniel Baena, Ella Gabitov, Laura B. Ray, Julien Doyon, and Stuart M. Fogel.
