Dr. Udi Ringel is leading the UNC brain imaging research project, which is looking at the brain response to intestinal stimulation using advanced imaging techniques with positron emission tomography (PET) and functional MRI. He is also looking at the effect of various physiological (e.g., intestinal smooth muscle tone/compliance, autonomic nervous system activity) and psychosocial (e.g., history of abuse, psychological stress) factors on upper and lower GI tract sensation. Dr. Ringel is also involved in studying clinical outcome of GI endoscopy.
