Dr. Johnson's lab is primarily interested in developing and refining neural interface technologies to improve the quality of life for people with movement disorders. Deep brain stimulation (DBS) is one such technology, which over the past twenty years has helped numerous patients with Parkinson’s disease, dystonia, and essential tremor reclaim control over their motor function. The therapy involves placing small electrodes in regions of the brain that exhibit pathological activity, which contributes to the movement disorder, and then stimulating those regions with continuous pulses of electricity. His lab focuses on understanding how the brain responds and adapts to such stimulation-based therapies from a combination of computational and experimental perspectives. The knowledge gained from these studies in turn provides us with a framework to develop, evaluate, and translate new approaches for improving patient outcome.
