Benign EEG Variants 

P.S: The tip of the tongue is relatively more negative and not positive relative to the base of the tongue.

The tip of the tongue is negative comparing it to the base. it's the opposite of the eye, where the cornea is relatively more positive than the retina

thank you very much

Again the best instruction on EEG. What is the software shown with different chapter options?

The polarity of the tongue is negative at the tip and positive at the base.
