Alpha-Band EEG Synchronization during Electrical Acupuncture

Abstract:

In the present study, the patterns of phase synchronization in an acupuncturing task were investigated. Neiguan (PC6) and Shenmen (HT7) are the main acupoints, they are both the main points for heart diseases and insomnia, epilepsy, mental disorder. The task was divided up into the following parts, the resting condition; needling sensation; needling with power on for 20 minutes; needling retaining and needling extraction. The index of phase synchronization in different parts was calculated and compared. Phase synchronization was increased in alpha band in many cognitive, attention tasks. These findings suggest that the transient network of coupled cortical regions maybe mediated through neural synchronization. The result in this paper shows that during electro-acupuncture about 15 minutes, the index between the available electrodes in the hindbrain, especially after electrode CP6, and all the available electrodes in the brain increased. That means phase synchronization increased between the hindbrain regions and whole brain during the electrical-acupuncture about 15 minutes. It could be an evidence of regulating both the peripheral nervous system and central nervous system with stimulating these two points.
