Research Interests

Dr. Wheaton's interests are in the neural control of higher order motor control in the upper and lower extremities. Research underway involves understanding how healthy people plan and execute complex tasks, including walking, kicking a ball, and using tools. As well, we are studying how neural networks change in people with stroke or cortical degeneration successfully plan and execute these tasks through rehabilitation or spontaneous recovery. We utilize electroencephalography (EEG), electromyography (EMG), imaging (fMRI) and behavioral analysis to explore these aspects of motor control.
