The Scientific Group considered the scalp acupuncture lines (Fig. 1-5) as well as the underlying functional zones of the brain (Fig. 6-7). It proposed the following nomenclature, using the alphabetic code MS (derived from “micro-system” and “scalp point”).

dingniè qiánxiéxiàn |

|

* These scalp acupuncture lines were formerly named in functional terms. The proposed standard international nomenclature is based on surface anatomy so as to facilitate localization of the lines, but their relationship to the underlying functional structures has not changed.
