Criteria for fibromyalgia patients. Inclusion Criteria: * Volunteers 18-50 years of age. * Fibromyalgia for at least the past 3 months, as determined by the referring physician. * At least a 10th grade English-reading level; English can be a second language provided that the patients feel they understand all the questions used in the assessment measures. Exclusion Criteria: * Specific causes of pain (e.g., cancer, fractures, spinal stenosis, infections) * History of cardiac, respiratory, or nervous system disease that, in the investigator's judgment, precludes participation in the study because of a heightened potential for adverse outcome. * Presence of any contraindications to fMRI scanning. For example: cardiac pacemaker, metal implants, fear of closed spaces, pregnancy. Criteria for healthy adults.

Exclusion Criteria: * Chronic and acute pain (ex. Fibromyalgia). * History of cardiac, respiratory, or nervous system disease that, in the investigator's judgment, precludes participation in the study because of a heightened potential for adverse outcome. * Presence of any contraindications to fMRI scanning.
