Summary
The objective of this trial is to measure the changes in neural activities during tDCS session using Magnetic Resonance Imaging (MRI). Participants (N=60) (20 Healthy Controls and 40 participants with neurological disorders, ie. multiple sclerosis) will be recruited to complete self-report measures and a brief cognitive assessment and then undergo an hour long stand-alone MRI scan while simultaneously undergoing tDCS stimulation. Methodology for this study is the administration of 15-minutes of of active tDCS during MRI acquisition compared to time without active tDCS.
