title: [P100 and N170 Components of ERPs in Abstinent Cannabinoid Users during the Modified Stroop Task].
abstract: In the current work we conducted the comparative analysis of P100 and N170 components of ERPs in abstinent cannabinoid users and in healthy controls during the modified Stroop task. The latency of P100 and N170 components was shorter in the temporal, parietal and occipital areas in abstinent cannabinoid users in comparison with the control subjects. The cannabinoid group showed the decrease of P100 amplitude in the right temporal and parietal areas and the decrease of N170 amplitude in the left temporal and parietal areas. There were no differences in the behavioral indices between these two groups. Thus, cannabinoids influence upon the mechanisms of early selection and these alterations of brain activity are stable and long-term.
