Effects of the EEG-neurofeedback on Cognitive Function

Executive function play a key role in boosting human behavioural performance. Based on scientific literature, it is still controversial whether electroencephalography-based neurofeedback (EEG-NFB) represents an effective technique for enhancing healthy adults' executive function. This study evaluates generalized effects of 3-week EEG-NFB training, using self-regulation of the theta to beta wave ratio (TBR), on executive function in healthy adults. The subjects are an uniform group of healthy young right-handed males divided into two equal groups. The trained group (TR) performs 3-week EEG-NFB training (three sessions per week) focused on a cognitive self-regulation of TBR (to achieve the lower TBR values as beneficial cognitive effect), while the control group (CO) does not participate in the EEG-NFB training. Cognitive function are rated before and after 3-week EEG-NFB training by psychological tests: Trail Making Test (TMT, parts A and B) and the Stroop Test (ST, parts I and II). This project is important for the future development of effective EEG-NFB protocols to be used by healthy people to improve their behavioural performance.
