“…The cathodal electrode was placed over T4 based on the 10-20 International System of EEG placement. T4 is associated with fine motor control and should not impact math/statistics calculation [16]. The control group experienced a sham condition with the tDCS.…”

“…Moreover, scalp locations under the EEG electrodes can provide very important information. Frontal midline (Fz) performs function of motor planning and parietal midline (Pz) is involved in perceptions [5]. A growing task load is associated with enhancement in the theta activity in Fz and reduced alpha activity in Pz [6].…”

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.

“…Increased coherence means that two particular areas are connecting excessively which may lead to decreased creativity or flexibility in cortical processing. On the other hand, decreased coherence which indicates less cooperation between regions, hence longer processing time is involved and less efficient in completing a given task [13].…”

In this research, we investigated the differences in brain activity while the subjects played video game. Experiment was conducted with two screen sizes; a large screen (40-inch display) and a small screen (3.5-inch handheld game). A total of 28 subjects participated in the study where two groups of 14 subjects played video games on two different screen sizes. Prior to video game play, baseline electroencephalogram (EEG) data were recorded during eyes open (EO) resting condition for five minutes. While the subjects played video game, the data were collected using a 19channel EEG machine. The analysis was made by comparing the EEG results of subjects playing video game with that of baseline data. In order to remove artefacts like eye blinking and eye movements, a pre-processing like filtering was performed to clean the data. The analysis was made by using three measures, i.e., absolute power, coherence and phase lag. The analysis was made on four main frequency bands. It was found that the brain was active in beta band as higher absolute power was observed in occipital, parietal frontal and motor regions while playing video game as compared to baseline condition. Also, the coherence results showed that these regions are well connected. Furthermore, faster communication was observed from phase lag result for these regions.
