The team, led by David Finn, Co-Director of Research Center of National University of Ireland, pain, first find out exactly how the brain "off" pain under stress
"The body can suppress pain during extreme stress with a similar marijuana substance that is produced in the brain. We first found that the hippocampus (a brain region involved, in particular, the ability to remember) plays an important role in the action of endocannabinoids, "- said the Finn was quoted as saying in a statement the university.
He and his colleagues were able to demonstrate that the cessation of production of the enzyme that breaks down one of these endocannabinoids in the hippocampus, extending the time of stress analgesia.
