Dr. Jeffrey Thompson began experimenting with sound and its effects on the body and brain in 1981 at his Holistic Health Center in Virginia. His experiments involved using exact sound frequencies to make chiropractic spinal and cranial adjustments, to stimulate and normalize organ function, and to balance acupuncture meridians. His clinical research with thousands of patients and volunteers led to groundbreaking discoveries in how sound frequency patterns, built into musical soundtracks, can entrain brainwaves and trigger numerous health benefits.
