Abstract

|
Objective:Audio-evoked potential is technique used for measuring brain functions such as memory, attention, and concentration. Although a number of studies on acupuncture for pain, there are few reports on the effect of acupuncture cognitive function.
Methods: Fifteen healthy volunteers with no neurological condition took part of the study. $(23.27{\pm}2.09)$. In this study, we examined the changes in auditory P300 by acupuncture stimulation to ’Oegwan’ on the left hand. Auditory P300 was recorded before, during and after acupuncture. The amplitude and latency of P300 at Fz, Cz, Pz point were calculated.
Results:Auditory P300 amplitude decreased during and after acupuncture, but there was no statistical significance.(P< .05) Auditory P300 latency significantly decreased during and after acupuncture.(P< .05)
Conclusion:The decrease of Auditory P300 latency time suggests that acupuncture at Oegwan has some effects on the cognitive function.
