Hi
I wonder, if there any difference between eeg recordig from the single electrode and multi-channel recording from the same electrode?
Thanks

Please explain how you intend to record EEG with a single electrode.

Actually, we performed EEG biofeedback sessions with single-channel on Pz
(of course, with ground and ear references, monopolar montage).
There were correlations between EEG spectral power and performance.
I know that multi-channel EEG recording is preferable. Thus, it isn't clear, whether we can base on EEG data from single channel only.

It seems to me that you are the one who should answer that question, it's basically the key issue of your research.
