This is a copy and paste of the info from the NIH studies department:
For the life of me I don't know how some of you cut and paste the way you do.
Title: Somatosensory Studies of Pain and Pain Control Measured with Oxygen-15 Water Positron Emission Tomography and Functional MRI in Normals and Patients with Neuropathic or Chronic Pain Conditions
Number: 92-D-0243
Summary: Regional cerebral blood flow (rCBF) will be measured while normal subjects, patients with post-operative pain, and patients with neuropathic abnormalities of pain sensation are exposed to a battery of somatosensory stimuli that activate
known pathways subserving touch, temperature and pain sensations. Patients with peripheral neuropathies and other chronic pain conditions that cause spontaneous pain, hyperalgesia, and allodynia (pain sensation to a normally non-noxious stimulus) will be examined with and without applied experimental stimuli. Data from the patient groups will be compared to those of normal controls. In addition, an ultrashort opioid analgesic will be administered to normally and select patients in order to map opioid modifications of pain neural activity. Activation of several somatosensory modality in conjunction with high resolution positron emission tomography (PET), adjunctive structural imaging with magnetic resonance imaging (MR.) and analgesic drug manipulations will functionally, anatomically, and pharmacologically characterize the physiology and pathophysiology of nociceptive in human beings.

I know this is pasted yucky but I hope that knowing that NIH does clinical trials, could be a help.
