Introduction. Problematic Internet Use (PIU) is often described as an umbrella term, covering a variety of different activities available due to the internet access. For some individuals, these activities have a potential to lead to an inability to control one’s use despite the negative consequences in daily life, what coincides with the definition of addiction. In this study we aim to evaluate the PIU relationship with mental health state and to investigate the response inhibition reflected by N2 and P3 components during Go/NoGo task and dopaminergic transmission indicated by Spontaneous Eye Blink Rate (sEBRs) during Resting State in a sample of non-clinical Internet Users. Methods. Subjects were divided into two groups (PIU Group and Control Group) based on the results of short version of Problematic Internet Use Questionnaire (PIUQ-9). A set of tests was used to monitor the presence of comorbidities: Barratt Impulsiveness Scale (BISII), Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI) and Clark-Beck Obsessive-Compulsive Inventory (CBOCI). EEG data were recorded during the auditory equiprobable Go/NoGo task and three electrodes (Fz, Cz, Pz) were selected for further investigation of N2 and P3 components. The sEBRs were assessed with an electrooculogram recorded from above and below the left eye and from the right and left outer canthi. Results. Problematic Internet Users (PIU) group demonstrated higher scores on Impulsiveness Scale and Obsessive-Compulsive Inventory compared to Control Group. P3 amplitude were higher in PIU group at Cz (p=0.032) and Pz (p=0.012) electrodes sites during Go condition. P3 amplitudes were also higher in PIU group during NoGo condition at Cz (p=0.032) and Fz (p=0.009) electrode sites. Lower N2 amplitudes were observed in PIU group during NoGo condition at Fz electrode site (p=0.022). In the group with PIU, impulsivity levels were inversely related to sEBR, and [...].
