![]() We therefore encourage a more comprehensive approach to EEG-neurofeedback training embracing physiological and/or operational relations among various EEG bands. Our study exposes the possibility (i) that the alpha band is more prone to manipulation, and (ii) that changes in the bands' amplitudes are independent from specified training. Parallel changes in the two bands challenge the idea of frequency-specific EEG-NFB protocols and suggest their interdependence. ![]() EEG changes were not matched by measured behavioural indices of attention. Group-independent increases in the activity of both bands were observed in the later phase of training. Up-regulation training induced increases in beta and alpha band (8-12 Hz) amplitudes during the first three sessions. Two groups of healthy adults were trained to either up- or down-regulate beta band activity, thus providing mutual control. We evaluated feedback manipulation in the beta band (12-22 Hz), known to be involved in visual attention processing. In this study, we administered EEG-neurofeedback ( EEG-NFB) to a healthy population to determine the efficacy of this procedure. The frequency-function relation of various EEG bands has inspired EEG-neurofeedback procedures intending to improve cognitive abilities in numerous clinical groups.
