SerpensV (1325715) writes "German scientists found direct evidence that spinal cord is involved in the placebo effect. According to "New Scientist":
"The researchers who made the discovery scanned the spinal cords of volunteers while applying painful heat to one arm. Then they rubbed a cream onto the arm and told the volunteers that it contained a painkiller but in fact it had no active ingredient. Even so, the cream made spinal-cord neural activity linked to pain vanish.
"This type of mechanism has been envisioned for over 40 years for placebo analgesia," says Donald Price, a neuroscientist at the University of Florida in Gainesville, who was not involved in the new study. "This study provides the most direct test of this mechanism to date."""
