In this work, the variation of the waveform of the movement related cortical potential (MRCP) was investigated in a real-time neurofeedback study, in which the spontaneous slow cortical potential (SCP) within the same frequency band as MRCP ([0.05 3] Hz) was provided as feedback to the subjects. Experiments have shown that the background SCP activity has a strong influence on the waveform of the self-paced MRCP. Negative potential SCP has been shown to increase the negative peak of the MRCP waveform, while positive potential SCP has been shown to reduce the negative peak. The variation of the single-trial MRCP waveform was correlated with the background SCP activity. This study provided a new approach to evaluate and modulate MRCP waveform, which directly determines the brain switch detection BCI performance.
