Headband electrode system

A headband electrode system comprising:

• an elongate flexible band;
• a center electrode mounted upon said band at a central portion of said band at a first elevation relative to said band;
• a pair of temporal electrodes;
• a pair of arm members each carrying one of said temporal electrodes, said arm members extending from said band to dispose the temporal electrodes at a second elevation relative to the band such that said temporal electrodes are below said center electrode, and pivotal mounting means connecting the arm members to the band, such that said arm members are pivotally mounted to the band, one to either side of the center electrode for mounting each of said temporal electrodes for pivotal movement relative to said band;
• said arm members being pivotally movable for positioning said temporal electrodes at a plurality of positions relative to said center electrode;
• and means for affixing said band to the head of a subject so as to position said center electrode substantially centrally upon the forehead of the subject and said temporal electrodes for pivotal movement beneath and to either side of said center electrode, said band comprising a relatively flat member of predetermined thickness over a major portion thereof and having two cross-sectional regions of decreased thickness which extends transversely and continuously across said band, one said continuous region of decreased thickness being disposed on either side of said center electrode to increase the flexibility of the band and facilitate the ability of the band to conform to the contour of the head of a wearer.
