Effect of neurofeedback training on auditory evoked potentials’ late components reaction time: A placebocontrol study

Background/Aim. Neurofeedback (NFB) training of sensorimotor rhythm (SMR) contributes to improving cognitive performance and increasing attention. SMR power is increased when a person focused task-oriented. The shorter reaction time (RT) the P300 auditory evoked potentials (AEPs) associated with better Hence, increase in after NFB should decrease RT task. aim study was examine ability healthy individuals modulate electroencephalographic (EEG) activity between 12 15 Hz during 20-day sessions. In addition, effect on investigated. Methods. Participants were divided into experimental control groups, 24 subjects (12 males females) each group, aged 25 40 years. group trained authentic training, while false (placebo) applied. AEPs registered five occasions: before 5, 10, 20 sessions, one month last training. Results. results showed that series sessions amplitudes SMR. significantly shortened, it not observed. Moreover, EEG signal o f t he S MR negative correlation RT, but only subgroup male subjects. Conclusion. obtained indicate effects improvement attention process expressed by RT.
