LIGHT AND SOUND STIMULATION CAN BE USED TO DULL CHRONIC PAIN, NEW STUDY SUGGESTS.
Studies carried out in the UK suggest that the brain can be ‘tuned’ to certain frequencies to alleviate chronic pain. Scientists discovered that alpha waves from the forebrain, associated with placebo analgesia, influence how the rest of the brain processes pain. Researchers used audio-visual stimuli — from goggles with flashing light or certain sounds — in the alpha range and found they effectively reduced pain, providing a potentially safe, simple and low-cost tool to treat chronic pain.
