Abstract
The human brain is constantly active, even at rest. Alpha coherence is an electroencephalography (EEG) rhythm that regulates functional connectivity between different brain regions. However, the relationships between resting-state alpha coherence and N2/P3 components associated with response inhibition and cognitive processes have not been investigated in addictive disorders. The present study investigated the relationships between alpha coherence during the resting state and N2/P3 components of event-related potentials during the Go/Nogo task in healthy controls (HCs) and patients with Internet gaming disorder (IGD). A total of 64 young adults (HC: n = 31; IGD: n = 33) participated in this study. Alpha coherence values at left fronto-central and bilateral centro-temporal electrode sites were significantly correlated with P3 latency in HCs, whereas inverse correlations were observed in patients with IGD. Furthermore, significant differences were observed in the correlation values between the groups. Our results suggest that patients with IGD lack dynamic interactions of functional connectivity between the fronto-centro-temporal regions during the resting state and the event-related potential (ERP) index during cognitive tasks. The findings of this study may have important implications for understanding the neurophysiological mechanisms linking resting-state EEG and task-related ERPs underlying IGD.
Highlights
Significant group differences were observed in education, Intelligence quotient (IQ), Y-Internet Addiction Test (IAT), Beck’s Depression Inventory (BDI), and Beck’s Anxiety Inventory (BAI) scores
Our findings suggest that the information-processing regulatory system in patients with Internet gaming disorder (IGD) was altered compared to that in healthy controls (HCs) during the transition from resting state to task activity
This study identified distinct patterns of associations between resting-state EEG alpha coherence and event-related potential (ERP) components elicited with the Go/Nogo task in HCs and patients with
Summary
In January 2020, the World Health Organization (WHO) declared the outbreak of the novel coronavirus (COVID-19) a global health emergency. COVID-19 has had a devastating impact on the lives of many and has resulted in physical and mental health crises [1,2]. Several studies reported an increased consumption of alcohol and Internet gaming behavior during the pandemic [4]. Addictive behaviors such as Internet gaming and Internet use are considered to be putative coping strategies to deal with the negative consequences of social isolation and loneliness [5,6]. Internet gaming disorder (IGD) is characterized by the persistent and recurrent use of Internet gaming despite negative consequences [7]
