Sleep deprivation (SD) has negative effects on emotional regulation, but few studies have evaluated electroencephalo-graphic (EEG) indices and none of these have used a within-subject design. Twenty-nine participants (17 female) com-pleted a repeated-measures study protocol involving a night of normal sleep (NS) and a night of SD, followed by resting-state EEG during the following morning. Established EEG indices of emotion regulation, frontal alpha asymmetry (FAS)and slow wave/fast wave (SW/FW) ratio in frontal sites (F3, F4, Fz), were investigated. Our results did not reveal SD ef-fects in FAS (t28= -.960, p = .345) or in SW/FW ratio (t28= 0.737, p = 0.467). Although other studies have demonstratedemotional dysregulation after SD, two well-studied EEG markers of emotional dysregulation did not reflect altered emo-tional states after SD in the current within-subject study. Future studies combining EEG and other indices of emotionalregulation may help elucidate these results.
