Abstract:
An electroencephalograph (EEG) electrode locator headgear, comprising:a base strap assembly adapted to be secured comfortably around the circumference of a user's head; an elastic, stretchable cap portion connected to said base strap assembly; a plurality of EEG electrode locators mounted to said elastic, stretchable cap portion for accurately positioning said plurality of EEG electrode locators relative to the user's scalp, and for biasing said plurality of electrode locators toward the user's scalp; and a plurality of EEG electrodes adapted to be received in and cooperate with said plurality of EEG electrode locators, respectively, each of said EEG electrodes including a plunger assembly adapted to prepare the user's scalp and to seat the electrode in one of said EEG electrode locators, said plunger assembly including a plunger member having upper and lower portions, and said plunger assembly including an electrically conductive spreader member mounted to said lower portion of said plunger member, said spreader member having a plurality of flexible, resilient fingers having distal ends biased to meet at a common distal central location, and said flexible, resilient fingers being adapted to spread apart by exertion of downward pressure of said plunger assembly against the user's scalp and to thereby part the hair of the user's scalp.
