Figure 10.

Topographical distribution of t values for the contrast in 18–30 Hz changes induced by type I slow waves between dream experiences (DEs), no experiences (NEs) (left), DE and dream experiences without recall of content (DEWR) (middle), and DEWR and NE (right), averaged over the last 60 s before the awakening. Electrodes within a cluster showing a statistically significant effect are marked in white (p < 0.05, cluster-based correction for multiple comparisons, two-tailed paired t tests: n = 12 subjects for DE; n = 11 subjects for NE; n = 13 subjects for DEWR).
