Loop-closure of the visual-cortical response

Results of a study designed to test the effectiveness of using feedback to consciously connect humans to their evoked response and thereby 'close the loop' around the brain are presented. A technique to achieve loop closure using a lock-in amplifier approach is presented. Findings indicate that conscious control of EEG (electroencephalogram) is possible. Each of the eight subjects tested was able to achieve control. Implications of these results in terms of brain-actuated control are addressed.<<ETX>>
