When the human body experiences physical trauma, pain receptors in the brain are activated. In very simplistic terms, some chronic pain is caused by these pain receptors being activated although not in response to a physical injury. The most extreme example of this is having phantom limb pain. Suffering constant and chronic pain when there should be no response means there is a glitch in the neural system. If we were a computer that was glitching, we’d likely be restarted. This is where Ketamine infusions come into play. They are the computer restart equivalent for human beings.
