Figure Legend Snippet: SWEs are characterized by varying IEIs both on intra- and interindividual level. ( A ) Three different exemplary EEG data segments of a single subject illustrate the variety of IEIs of SWEs. The rows show epochs (≈ 18 s) of artifact-corrected EEG signal of channel Fz. ( B ) Box-whisker plot shows the distribution of IEIs of all SWEs detected in this study. ( C ) Depiction of median IEIs of n = 17 individual sessions. ( D ) Box-whisker plots illustrate the distribution of peak amplitudes (μV) of all SWEs occurring in wakefulness, in sleep stage N1, in sleep stage N2, and in sleep stage N3, respectively. Mann–Whitney U tests indicated that peak amplitudes of awake SWEs (Mdn = 81.2 μV) did not significantly differ from the peak amplitudes of N1 SWEs (Mdn = 81.2 μV) ( U = 2093, P = 0.85), of N2 SWEs (Mdn = 84.6 μV) ( U = 174 773, P = 0.19), and N3 SWEs (Mdn = 78.1 μV) ( U = 349 908, P = 0.08). Furthermore, peak amplitudes of N1 SWEs did not significantly differ from the peak amplitudes of N2 SWEs ( U = 20 037 , P = 0.74) and N3 SWEs ( U = 32 900 , P = 0.4). However, the peak amplitudes of N2 SWEs and N3 SWEs significantly differed from each other ( U = 2 753 639 , P < 0.001). ( E ) Box-whisker plots show the distribution of durations (ms) of all SWEs appearing in wakefulness, in sleep stage N1, in sleep stage N2, and in sleep stage N3, respectively. Although the durations of SWEs occurring in wakefulness (Mdn = 620 ms) did not significantly differ from the durations of N1 SWEs (Mdn = 765 ms) ( U = 1870 , P = 0.85), they were significantly longer than the durations of N2 SWEs (Mdn = 540 ms) ( U = 157 876 , P < 0.001) and N3 SWEs (Mdn = 525 ms) ( U = 269 824, P < 0.001). Likewise, the durations of N1 SWEs were significantly longer than the durations of N2 SWEs ( U = 14 927, P = 0.02) and N3 SWEs ( U = 25 404, P = 0.01). There was no significant difference between the durations of N2 and N3 SWEs ( U = 3 084 885, P = 0.09).
