Cz
halfway between Nasion and Inion. The
frontopolar and occipital electrode positions should now be placed correctly. Otherwise choose
another cap size. When measured correctly, the frontopolar electrodes (e.g.
Fp1/Fp2
) should lie
directly above the eye brows.
Make sure, that
Cz
is right-left-centered as well, and that lateral electrode positions are
symmetrical.
Affix the cap with the chin belt. Pay attention to the correct location of its. The wide part of a belt
should fit a chin and shouldn’t slump on the neck. The belt tension should provide reliable fixing
of cap.

effective in cases where during the test pressure of the chin strap hinders the patient's actions,
for example, if the patient should talk.
The chest belt is attached directly to the patient's chest. Chest belt is arranged in V-shape or X-
shape, which contributes to a secure fit of the cap. Tension is regulated by the length of the
