Published in “Alternative Therapies Health Medicine”(Ogura 2011)(2), this study was done by 8 PhD’s and 1 Chiropractor. They used a PET scan as a powerful neuro-imaging technique to measure neuronal activity in the brain.
They were able to take a radioactive analogue of glucose as a marker to measure brain glucose consumption as it would indicate brain metabolic activity post-adjustment. Their findings were ASTONISHING!!
The study clearly demonstrated that the sympathetic tone of the nervous system was inhibited, salivary amylase was decreased (indicating a decrease in fight/ flight physiology), regional brain metabolic changes occurred, and muscle tone & pain intensity decreased following ONE single chiropractic adjustment.
