The Relationship Between QEEG Waves as a Neurophysiological Markers in F_P1 / F_p2 Areas and Multiple Aspects of Impulsivity

Abstract

Background: Impulsivity is an important factor associated with high risk behaviors. The new findings reveal the neuropsychological bases for this personality trait. Objectives: The current study aimed to investigate the relationship between quantitative electroencephalography (QEEG) connectivity indices in FP1 / Fp2 brain areas and multiple facets of impulsivity among college students. Patients and Methods: The current correlational study was conducted on all students of the University of Mohaghegh Ardabili in 2015 - 2016 the academic year as the statistical population. Eighty-eight students were randomly selected and asked to respond to the questionnaire of demographic information and impulsive behavior scale, then they were brought into the laboratory of psychology, located in the Faculty of Educational Sciences and Psychology of the University of Mohaghegh Ardabili and their EEG activities were recorded for six minutes both under opened eye and closed eye conditions. The data were analyzed with NeuroGuide and SPSS version 23. Results: The current study results showed a positive relationship between negative urgency and delta activity in closed eye condition in FP1 / Fp2 areas. Also, beta activity in opened eye condition in FP1 / Fp2 areas was negatively correlated both to lack of premeditation and positive urgency. Moreover, there was a significant relationship between high beta activities in closed eye condition and the lack of perseverance. Conclusions: The obtained results were consistent with prior findings highlighting the importance of the high beta and low delta activity in prefrontal lobe in impulsive behaviors.
