<div dir="ltr"><div><div>Dear EEG experts, <br></div> I would like to acquire some datasets for investigating a potential located in the frontal medial line (like the Error Related potential, e.g. ErrP and ERN) and I'm doubtful about the ground position.<br>
</div><div>I always locate the "reference" electrode on the ear lobe with a clip and the ground in the Cz electrode. But, in this case, I want to check the presence of a potential located in the midline frontal and I think that the ground on Cz isn't the best solution.<br>
<br></div>Some experimenters use forehead <span class="">ground to investigate the ErrP and other ones use the mastoid ground. </span><br><div>I've got a maximum of 32 electrodes (I'm specifying this for the common average reference issues).<br>
<br></div><div>Can anyone suggests me what is the best ground location?<br><br></div><div>Thanks in advance<br></div><div><div><div><br clear="all"><div><div><br>-- <br> -Michele-
