An EEG electrode system for establishing positive electrical contact with the scalp, uses absorptive electrode wrap material in contact with metallic electrodes, with saturated electrode wrap material placed in contact with the scalp. Saturation of the electrode warp material with a conductive solution such as saline provides mechanically and electrically stable contact at multiple scalp electrode sites. An electrode wrap holder assembly holds the electrode wrap and an exposed portion of the electrode wrap in contact with the scalp, while providing access to the electrode wrap for re-wetting with the conductive solution if required. The electrode wrap holders are mounted in straps, hard caps or other headgear. Adjustment of the electrode wrap holders within the mounts further compresses the flexible, absorptive electrode wrap, causing flow of the conductive solution therein and enhancement of the electrical contact.
