Physionet EEG Motor Movement/Imagery Dataset referenced to what channel?

Post by hayder » 26 Dec 2015, 16:37

Hi there,

I want to import the Physionet EEG Motor Movement/Imagery Dataset to Neuroguide software. I had to edit the headers of the EDF+ files, since the naming of the channels should match that used in Neuroguide. However, I had not found anything indicating to what are the EEG readings referenced exactly. A commonly used reference are either A1 or A2 or linked ears or sometimes one of the EEG channels. I read the two papers mentioned in physionet site and several other papers used the dataset, but all of them did not mention the referencing.

Appreciate if you know what is the reference used in the EEG dataset recording.

Thanks
Haider
