In this paper, we test the hypothesis that free-water in … Continue reading →

https://www.ncbi.nlm.nih.gov/pubmed/31794958 OBJECTIVE:  Essential tremor (ET) prominently affects the upper-limbs during voluntary movements, but can also affect the lower-limbs, head, and chin. Although deep brain stimulation (DBS) of the ventral intermediate nucleus (VIM) of thalamus improves both clinical ratings and quantitative … Continue reading →

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 →

Article here Abstract Progression markers of Parkinson’s disease are crucial for successful therapeutic development. Recently, a diffusion magnetic resonance imaging analysis technique using a bitensor model was introduced allowing the estimation of the fractional volume of free water within a … Continue reading →

Abstract Burciu et al. (2017) https://www.ncbi.nlm.nih.gov/pubmed/28594097 Cervical dystonia (CD) is the most common type of focal dystonia, causing abnormal movements of the neck and head. In this study, we used noninvasive imaging to investigate the motor system of patients with … Continue reading →
