Re: Delivering electric shocks while recording EEG

Thanks!! We will check the galvanic isolation issue with Biopac. During offline processing, we regularly re-reference the data to the average of the two electrodes placed on the mastoids. This does not eliminate the noise in this case... Do you think there is anything at all we could do online (in a...

Hi, We have a new experiment that involves delivering electric shocks (using Biopac stimulator) while recording EEG with BioSemi. We have noticed that while the stimulator is on, the EEG data looks clean, same as when the stimulator is turned off. However, when we attach the two electrodes from the ...
