What is the electrical principle behind an EEG?
What is actually moving (?electrons), why is it moving, and how do we pick up the amount and direction of movement?
What is the relation between movement of electrons and electrical field?
What are the electrodes on the surface of the scalp actually picking up?
How is the electric field in scalp recording different from ECG?
What is really meant by potential difference?
