Over the past twenty years, scientists have been exploring how chiropractic care affects a person’s nervous system and they have found that chiropractic care undoubtedly changes the brain. And, chiropractic adjustments change a part of the brain called the pre-frontal cortex. The prefrontal cortex is an area of the brain that is heavily involved in emotional control, and it influences our behaviors by dampening what is called the brain’s limbic system. The brain’s limbic system is your emotional brain, your threat detector is there and it is always on high alert looking for dangers. And the prefrontal cortex calms down that limbic brain.
