Official title
Brain Activation During Accommodation to Painful Stimulation With Functional Imaging of Pain
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Blood oxygen level dependant (BOLD) functional magnetic resonance imaging (FMRI) investigations of pain have provided substantial insight into the workings of the human brain. To date, however, the vast majority of studies have dealt with short painful stimulations. This work will expand the investigators knowledge of how longer stimulations are processed by comparing the activation pattern from a two minute painful stimulation with that of an 30-second painful stimulus. The investigators hypothesis that accommodation to the longer stimulation will be evident by either decreases in signal intensity in brain areas known to process pain, or by increasing activity in brain areas thought to be responsible for the modulation of painful perception.
