Sleep strengthens resting-state functional communication between brain areas involved in the consolidation of problem-solving skills

Seed to whole-brain analyses using a 3 × 2 group (sleep, nap, and wake) by session (rest 2 and rest 3) ANOVA demonstrated changes in functional connectivity between the hippocampus and SMA (A) and between the putamen and anterior cerebellum (B). Both omnibus effects were specific to the sleep versus nap comparison, as suggested by follow-up 2 × 2 group by session ANOVAs (Table 1). Spheres represent seeds.
