Brief Summary

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.

Study Arms (2)

TR group

EXPERIMENTAL

The training group (TR) will undergo 3 weeks of electroencephalography-based neurofeedback (EEG-NFB). EEG-NFB training.

Behavioral: electroencephalography-based neurofeedback (EEG-NFB)

CO group

NO INTERVENTION

Control group (CO) will not undergo 3 weeks of EEG-NFB training.

Interventions

The EEG-NFB training program will involve nine training sessions (three times a week over a 3-week period) each lasting 30 min. EEG-NFB training will be conducted with ProComp Infiniti Encoder and BioGraph Infiniti Software v.5.1.3. The training protocol will be set to decrease the EEG TBR value. For the 12 training sessions, all participants will be subjected the same EEG-NFB protocol at C3 electrode. The EEG-NFB training sessions consists of a 20-s baseline period (i.e., with no feedback), 30-min feedback presentation, and another 20-s baseline period. Subjects will be seated in front of a computer screen and animations will be used as feedback; the animation starts when the subject is sufficiently focused for 20 s. Three 10-min animations (flying duck, roller coaster ride, and moving ball) will be shown to the subject during each EEG-NFB training session. The raw EEG signal, TBR value over time, EEG signal noise, and EEG theta and beta wave amplitudes will be recorded.
