Download Paper Abstract We investigated the effect of acute levodopa administration on movement-related cortical oscillations and movement velocity in Parkinson’s disease (PD). Patients with PD on and off medication and age- and sex-matched healthy controls performed a ballistic upper limb … Continue reading →

We are actively recruiting PhD students for the Fall 2018 semester. We use a range of systems neuroscience techniques that include functional magnetic resonance imaging (fMRI), structural MRI, diffusion imaging (DTI), electromyography (EMG), high-density electroencephalography (EEG), and pain stimulation procedures. … Continue reading →
