Does the cortical response to electroacupuncture depend on stimulation frequency? Results of a pilot EEG study first proposed at the AACP Conference in 2001

EEG (electroencephalography) is a low-cost, accessible method of investigating electrical brain activity that is sensitive to rapid changes (unlike fMRI). Electroacupuncture (EA) and Transcutaneous Electrical Acupoint Stimulation (TEAS) are methods of acupuncture-like stimulation. This pilot crossover study, first proposed at the 2001 AACP Conference,1,2 explores the relationship between frequency of TEAS applied peripherally and frequencies of cortical electrical activity detected centrally.
