Concomitant tDCS and EEG

[Jochen]

Hello,

I am trying to use the BioSemi active two EEG system during tDCS stimulation (1mA; Neuroconn tDCS plus) but it seems, that after a while some of the EEG-electrodes close to the stimulation electrodes get saturated (offsets are off scale and the channels do not seem to yield EEG signals). This lasts on during stimulation and for a while (up to minutes) after. So i wanted to ask, if this is normal, or if there is anything i can do to prevent this.
Thank you very much in advance for your help.

Best regards,
Jochen

Hi Jochen,

Just wondering if you had any success finding a solution for your saturated electrode problem?

Regards,
