Ressonância Magnética Funcional (fMRI)
The use of functional MRI (fMRI) in neurophysiological pain research and, in a lesser extent, in clinical practice, is an ever-growing field. Research efforts in this field have uncovered the mechanism of brain response to different types of stimuli in health and disease. Imaging pain requires thermal stimulators that can safely and accurately deliver noxious and non-noxious stimuli within a neuroimaging environment for extended periods of time.
