EEG Acupuncture Study Proves Chinese Medicine Practice
As a result of a recent study that measured specific acupuncture points by EEG, researchers discovered that acupuncture has a “greater influence on the attention function of the brain.” The goal of the study was to investigate the effects of needling two main acupuncture points (Ht7 and Lu9) on human attention brain function and also to explore methods to research brain function as it relates to acupuncture stimulation.
The researches used EEG (electroencephalography) to measure ERP (event-related potentials). EEG measures electrical activity of the brain and ERP is a measure of brain responses related to thought and perception. ERP is an electrophysiological measurement of stimuli to the brain. Researchers looked for changes in P300, a brainwave reflecting cognitive function in decision making processes, after application of manual acupuncture at Ht7 and Lu9.
EEG brainwaves now measure what has been known to Chinese medicine for thousands of years. Ht7 (Shenmen, Spirits Gate) is an acupuncture point at the wrist crease known to be calming and restful to the heart and ‘spirit’. It is traditionally used for mental restlessness, mania, palpitations, disorientation, depression, and poor memory. Lu9 is known more for its affect on lung disorders so it is not surprising, from a Chinese medicine perspective, that EEG measurements more strongly connect Ht7 to changes in brainwave states associated with attention and cognition.
