Acupuncture analgesia involves modulation of pain-induced gamma oscillations and cortical network connectivity

“We examined the analgesic effects of verum in comparison to sham acupuncture on laser-induced pain using a double-blind controlled study design in healthy participants. Our analysis focused on the modulation of laser-induced gamma oscillations in pain-related brain regions and on changes of inter-regional coupling in this frequency band by acupuncture. Verum treatment diminished pain more than sham treatment. ”
