Early versions of the gate control theory of pain proposed that there were "gates" in the spinal cord that could block or allow pain signals to pass through. However, recent research has shown that pain control mechanisms also exist in the brain itself. These include the release of natural painkillers like endorphins and the activation of descending pathways from the brainstem that inhibit pain signals.
