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

D. Baena, E. Gabitov, et al.

Sleep's slow wave–spindle (SW‑SP) coupling selectively reactivates motor memories in the hemisphere that learned the sequence, with reactivations time‑locked to coupled SW‑SP complexes in task‑critical areas, while uncoupled spindles recruit primary sensory regions and may support sleep maintenance. Research conducted by Daniel Baena, Ella Gabitov, Laura B. Ray, Julien Doyon, and Stuart M. Fogel.
