Which reference is appropriate for the scalp ERP and EEG studies? This unsettled problem still inspires unceasing debate. The ideal reference should be the one with zero or constant potential but unfortunately it is well known that no point on the body fulfills this condition. Consequently, more than ten references are used in the present EEG-ERP studies. This diversity seriously undermines the reproducibility and comparability of results across laboratories. In 2001, we provided a new technique: the reference electrode standardization technique (REST) which may result in an approximate zero reference, and it has been confirmed repeatedly being the most competitive unipolar reference when compared with the popular average reference (AR), and linked-mastoids/ears reference (LM).

Simulation: same neural activities, different recordings when different references are adopted, and only REST with baseline close to constant zero.
