title: Changes of cerebral endogenous evoked potentials by acupuncture stimulation: a P300 study.
abstract: The change of cerebral potential P300 in relation to superior cerebral functions by means of acupuncture stimulation was studied. For this purpose, the parameters of this cerebral response after acupuncture stimulation at acupoints He-7 and LI-4, and at a non-acupuncture control point, have been assessed, both immediately after the stimulation and within the following 15 minutes. A considerable change is observed in the P300 amplitude after stimulation at He-7 acupoint, which increases with time. No changes due to non-acupuncture point stimulation or LI-4 acupoint stimulation are detected. These findings seem to support the real action of He-7 in different neuropsychological processes.
