“Assessment of tDCS-Induced Neuronal Responses in Multiple Sclerosis (MS) With Advanced MRI”
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.

Active tDCS
The simultaneous tDCS will be performed at up to 2 mA dose intensity to determine CMRO2 changes from when the tDCS is on when the tDCS is off. The stimulation (left anodal at DLPFC regions) consists of 15-min up to 4 mA tDCS using 5x5 cm electrode sponge with ~30s ramp-up and ramp-down periods.
Sham (placebo) stimulation
MRI-compatible tDCS off (immediately before and after tDCS)
