(b) Amount of each states (%) per recording file. (c) Average episode duration (s). (d)–(g) A comparison of the EEG spectral profiles for each of the three human experts and SleepEns across each of the four sleep–wake states, demonstrating close similarity. *p < .05 and ***p < .001 indicates significant differences.
