Association of EEG Scalp Potentials with Autonomic Innervations of Heart

Cerebral activation and autonomic nervous system have significance in studies such as mental stress. This study aims to analyse variations in electroencephalogram (EEG) scalp potentials that may influence autonomic innervations during video games. Twelve healthy participants (two females) were recruited in this study. EEG and electrocardiogram (ECG) signals were measured during game playing and rest condition. Sympathetic (high heart rate (HR)) and parasympathetic (lower normalized high frequency (HFnu)) innervations from ECG were evaluated from heart rate variability (HRV). Meanwhile ratio of theta at Fz to alpha at Pz power (Fz(θ)/Pz(α)) was calculated from the EEG scalp potentials to measure workload.
