Scalp Acupuncture: Two standard lines to locate stimulating areas [1]

To define the stimulating areas, it is necessary to establish marking lines over the scalp according to some demarcations on the surface of the skull.

Anterio-posterior median line: this median line is drawn from the midpoint between the eyebrows to the lower border of external occipital tuberosity.

Supraciliary-occipital line: this line is drawn from the midpoint of upper border of eyebrow to the tip of external occipital tuberosity.
