Sleep spindles track cortical learning sites

(A) Grand average (mean ± 95% CIs) of spindles and SOs at electrode position Cz. Amplitude, duration, and density were extracted for each participant and channel (see Table S2 for corresponding descriptive data and Figure S2 for group-level topographies).

(B) Across participants, encoding topographies were significantly more strongly correlated with topographies of spindles than SOs (density plots, group means, 95% CIs, and single participant data are shown. ^∗∗p < 0.01. ^∗p < 0.05).
