An array of analytical scalp electrodes preconfigured within a head-worn device designed for the rapid placement and appropriate positioning of the scalp electrodes during electroencephalography (EEG). It typically consists of a cap-like device with integrated scalp electrodes, and shielded lead wires that terminate into a connector that mates with a separate cable. The device eliminates the need to glue or paste individual electrodes to the patient’s scalp. This is a single-use device.
