FIGURE 2.
Automatic detection of microsleep episodes (MSEs) and driving performance in the driving simulator after sleep deprivation. Data were analysed until sleep onset. (A) Displayed for one representative participant: automatically detected MSEs (light blue) with sleep onset (black bar), off-road events (OFF, orange), lateral car position (LP, dark blue; 0 = centre of the road, off-road > ± 1000) and standard deviation of lateral position (SDLP, black) calculated in a 10-s moving window. Driving performance and EEG derived MSEs might be 1–2 s out of synchronisation. Data of all participants are provided in Supplementary Figure S2. Driving performance of all participants as measured by (B) number and (C) duration of off-road events (OFF), and (D) SDLP (10-s moving window), were calculated for the subsequent minute after each MSE onset (“MSE”), and the rest of the recording (“non-MSE”). ∗Significant difference (p < 0.05).
