There was a participant in the experiments today and we were not able to set the common/ground (the blue light on the box) to work. Even though, when I touched the electrodes, common/ground was set (the blue light) but not for him. This was both on the EEG and separated CMS/DRL electrodes.
What is the reason for this effect of not able to set the common/ground?
Unable to set common/ground for participant
