Dopamine is the secret behind the "placebo effect"

If person placebo effect, it means that he is the proud owner of a specific genetic sequences, reports BBC. This sequence of Professor Edzard Ernst of the University of Exeter has revealed some 104 people from the group of volunteers. All participants had irritable bowel syndrome.

Turned out, those who had a particular version of the gene COMT, began to feel better after placebo treatment (in this case, it was an imitation of acupuncture). True, scientists do not yet know whether this mutation only to irritable bowel syndrome, or associated with the placebo effect at all.

As for the present study, the volunteers are divided into three groups. First treated in a standard way with the official approach. The second – with the participation of caring health professional. A third group was not treated at all. Three weeks later, the patients interviewed about their condition.

Moreover, the researchers took blood samples. They were interested in gene catechol-O-methyltransferase (COMT). This gene is involved in the chemical dopamine way, giving a pleasant feeling. Apparently, when a person responds to a placebo activates neurotransmitter dopamine.
