Brain’s Hidden Pain Controller: How Enkephalins Could Shape Thai Pain Care
New research uncovers how the brain quietly governs pain, revealing a natural analgesic system that can dampen pain before it reaches our conscious mind. Central to this process is the periaqueductal gray (PAG), a brain region that can suppress pain signals and alter our experience of injury. This insight helps explain why some severely injured individuals—such as soldiers in past wars—felt little pain and points toward safer, non-opioid pain strategies.
