Association of Autonomic Nervous System and EEG Scalp Potential During Playing 2D Grand Turismo 5

Abstract

Cerebral activation and autonomic nervous system have importance in studies such as mental stress. The aim of this study is to analyze variations in EEG scalp potential which may influence autonomic activation of heart while playing video games. Ten healthy participants were recruited in this study. Electroencephalogram (EEG) and electrocardiogram (ECG) signals were measured simultaneously during playing video game and rest conditions. Sympathetic and parasympathetic innervations of heart were evaluated from heart rate variability (HRV), derived from the ECG. Scalp potential was measured by the EEG. The results showed a significant upsurge in the value theta Fz/alpha Pz (p<0.001) while playing game. The results also showed tachycardia while playing video game as compared to rest condition (p<0.005). Normalized low frequency power and ratio of low frequency/high frequency power were significantly increased while playing video game and normalized high frequency power sank during video games. Results showed synchronized activity of cerebellum and sympathetic and parasympathetic innervation of heart.

Probing ECG-based mental state monitoring on short time segments

“…V. DISCUSSION As expected, statistical analyses revealed a negative influence of WKL and TOT condition on both behavioral performance and subjective feeling. Regarding TOT, in keeping with the literature, the HF component of the HRV increased with it [9,10,16]. Moreover, although classification was performed on very short time segments (5s), good performance was achieved using HR and HRV for TOT assessment (65 %).…”

Dynamics of Scalp Potential and Autonomic Nerve Activity during Intelligence Test

“…LF/HF ratio was increased (χ 2 (2) = 5.33 and p=0.06) and Hfnu was decreased (χ 2 (2) = 4.33 and p=0.10). This result is consistent with the finding of [9] in mental arithmetic task and with [7] in playing video game.…”

“…These are responsible for heart-brain relationship [9,10]. Heart behaves excitation and inhibition under SNS and PSNS influence, respectively.…”

“…Further, the LF and HF can be expressed in normalized unit (nu), where nu is equal to LF or HF divided by total power minus VLF value. LF in normalized unit (LFnu) is attributed to sympathetic and the ratio of LF and HF is representation of sympathetic to parasympathetic distribution [9]. Recent ECG and EEG studies reported changes in ANS activity with mental arithmetic task [11].…”

Brain Behavior in Learning and Memory Recall Process: A High-Resolution EEG Analysis

“…learning, working memory, short-term and longterm memory [6], decision-making, intelligence tests [7], mental arithmetic tasks [8], problem solving under stress, playing video games [9], pattern-matching, and recognition [10]. Changes in EEG measures and features have been associated with these cognitive activities [11].…”
