Transcranial Magnetic stimulation alters cortical connectivity in Parkinson’s disease (PD) imparting clinical benefits. The mechanisms by which this occurs remain unexplored. In this study, Multivariate pattern analyses of task-based connectivity was carried out to understand the effects of rTMS in PD. Visuospatial task based functional MRI was acquired before and after stimulation sessions. Correlation matrices revealed an increased connectivity between left supplementary motor area (SMA) and left primary motor area (M1), suggesting an improvement in the motor network.
