It is typically done with the electrodes placed along the scalp, hence it is a painless procedure. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain.
EEG is most often used to diagnose epilepsy/seizures/fits, which causes abnormalities in EEG readings. It is also used to evaluate
