Under extreme conditions, the activity of the periaqueductal gray (PAG) can inhibit neural activity in the spinal cord that results in less pain signals being sent to the brain. This can help to relieve pain. The PAG also plays a role in modulating pain perception through the release of endogenous opioids such as endorphins, which can further reduce pain sensitivity. However, this alone does not fully explain how the PAG helps to relieve pain under extreme conditions.
