This Neurofeedback application is based on Motor Imagery of the feet. You will find it in share/openvibe/scenarios/bci-examples/neurofeedback.

  • neurofeedback.xml: This scenario replays a MI session and shows the real-time feedback the user was given during the session. The feedback is presented through signal displays : one for the brain activity on the Cz electrode, and one for the band power in the beta activity,related to (imagined) feet movement.

Please note that the Crop and Simple DSP configuration is based on a calibration session, that computed the Mean and Variance of Beta activity on Cz on a 30 sec inactivity phase.
