OK, a naive question...
biosemi 64-channels:
The EXG1-8 electrodes- the ground is also CMS?
(i.e. if there is a response on the earlobes/mastoids (EXG1-EXG8)- will it be due to activity measure at the CMS?)
thanks...

32 channels (64-channels cap)
Hi all
I have a cap with 64-channels
If I want to record only the R hemisphere (for saving time)- 32 electrodes.
If I attach the CMS and DRL, Will the results will be reliable?
thanks

ERP- Reference (Earlobe)
Hi. My lab purchase EEG (64 channels). So... I did a simple experiment: a tone (duration: 200msec, 70db, 1KHz) was repeated ~300 times. Subjects were ask to close their eyes and count the number of tones. After averaging, I get 2 clear peaks on the earlobes and mastoids: P1=~120msec, P2=~250msec (ma...
