Spectral power (SP) ratios of the EEG α and β frequencies were used as neurofeedback (NFB) for ten apparently healthy subjects (university students) to control a computer cursor in a graphic interface in three scenarios. The results showed that the scenario that used the SP ratio of the α and β 2 frequencies pro vided for the highest accuracy and best speed of task performance. The ratios including the β 1 frequency were found to be less efficient because an increase or a decrease in its SP could occur together with an increase or a decrease of the SPs of the α and β 2 frequencies. However, the subjects acquired the skill of controlling the cursor with an efficiency of 81%, which gradually grew during learning, after a relatively short period of time (5 training sessions within 2 weeks).
