Effects of prolonged wake on NREM EEG power spectra during recovery sleep. (A,B) Relative EEG power spectra for the AB and DS experiments averaged across 185 channels (mean ± SEM, n = 16) during NREM recovery sleep relative to BSL. Gray bars indicate significant bins (2-tailed paired t-test; P < 0.05). (C,D) Topographic distribution of t-values from paired t-tests contrasting relative power changes between the AB and DS recovery nights in the 1-11 Hz frequency band. Negative values indicate changes in the opposite direction. Channels showing significant increase in spectral power in AB relative to DS are indicated by black dots (P < 0.05 SnPM supra-threshold cluster analysis; note that in C the cluster size does not exceed the minimum threshold cluster size for significance (i.e., n = 2). Thus, the dots for C correspond to P < 0.05, uncorrected).
