Brief Summary
The placebo effect is a phenomenon that has experienced major advances of its understanding in the last decade. However, mechanisms of placebo analgesia in chronic pain patients have yet to be compared to healthy subjects. The investigators study aims to investigate the magnitude of placebo response and related opioid release in patients that suffer from episodic migraines as compared to healthy controls. In particular, the investigators are looking to map brain activity during placebo analgesia using modern brain imaging techniques such as functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET). The investigators hypothesis is that placebo response and the availability of opioid receptors is reduced in chronic migraine patients.

Outcome Measures
Primary Outcomes (1)
Visual Analogue Scale (VAS) 0-10 Pain Rating
This study will investigate how placebo may reduce experimental pain induced by contact heat. Patients rate heat stimulus intensity on a 0-10 scale, where 0 is no pain, and 10 is most intense pain possible. Data is reported to the placebo condition. The Visual Analogue Scale (VAS) consists of a straight line with the endpoints defining extreme limits such as 'no pain at all' and 'most intense pain possible'. The patient is asked to mark his pain level on the line between the two endpoints.
