a Each dot represents a stimulus from the original full pool (n = 1008 stimuli) plotted with respect to its z-scored valence (x-axis) and arousal (y-axis). Colored dots represent the selected stimuli for negative (blue), neutral (yellow), and positive (red) valence. b Experimental paradigm. Each participant completed an overnight EEG session and a wakefulness session, the latter including an EEG recording during stimulus presentation and an affective rating task. Vocal burst stimuli were presented in random order during NREM sleep and wakefulness experimental sessions.
