The placebo effect is when somebody's physical or mental health appears to improve after accepting a placebo or 'dummy' treatment.
<h3>How does the placebo effect result in the brain?</h3>
The placebo effect increases activity in an area called the rostral ventromedial medulla, which transfers pain information, and reduces activity in the periaqueductal gray, which helps the body suppress pain. The nocebo effect generated the opposite change.
In anticipation of benefit when a placebo is administered, dopamine receptors are started in regions of the brain associated with prize. As further evidence that the placebo effect is a authentic biological phenomenon, genetics can influence the strength of the effect.
