Hi All,

I have collected eeg with ActiveTwo for around 20 participants. All offsets are either positive or negative with approximately equal amount. But today, I found something unusual that is almost all offsets are negative, cf. the attachment. Is that usual?

Best,

Yes, normal, so long as everything is within -50 mV and + 50 mV all is fine.
