Current Research Interests

Virtual Reality and real-time fMRI
Applications of real-time fMRI Phase II
The goal of this study is to use real time imaging of the functions of the human brain to train patients to change activations in brain regions that control the experience of pain. Using fMRI, we are able to visualize activity taking place in brain areas involved in the perception and control of pain. By visually feeding back the subjects/patients own brain signal we are training them to learn how to control and change their pain experience. If successful, this allows patients to have greater control over their own pain. Several studies underway use fMRI to assess treatment and identify the most effective brain regions and cognitive strategies.

Cortical Restructuring in Patients with Chronic Pain
Recent research has demonstrated that chronic pain can induce changes in the brain that can amplify and maintain the pain experience. We are characterizing this phenomenon in patients with a variety of chronic pain conditions using a variety of neuroimaging techniques. We are following these preliminary studies with further investigations into the effects of treatment on reversing the brain changes induced by chronic pain.
PI: Dr. Sean Mackey

Cognitive Load and Perceived Pain Intensity
The aim of this study is to examine the role of attention in the experience of pain using a cognitive load task. We use various cognitive loads and thermal heat temperatures in order to determine how cognitive load can influence the experience of pain in both healthy and pain patients. By better understanding and characterizing this phenomena, we can design more effective therapies to help those with chronic pain.
