Electrode Harness![]() The Harness consists of 7 recording electrodes (Fz, Cz, Pz, F3, P3, F4, P4) according to the 10-20 system, 2 linked mastoid electrodes (M1 and M2), and 1 common electrode integrated into a comfortable, user-friendly design. The Electrode Pods are attached to a net of small diameter elastic tubes. The Harness is held in place with an adjustable Chinstrap and a Backstrap at the back of the head.
EEG signals are picked up via a small metallic ring inside each Electrode Pod. This ring does not actually touch the subject’s head. Instead, the Electrode Pods provide a port into which Biosensors are inserted. The Biosensors couple the electrical signals from the subject’s scalp to the metallic ring.
