Participant milestones

Participant milestones
Measure	Transcranial Direct Current Stimulation Active tDCS for 30 minutes daily for 4 sessions Transcranial Direct Current Stimulation: tDCS is a form of noninvasive, painless, brain stimulation that uses a mild direct electrical current passed between electrodes on the scalp to modify neuronal membrane resting potential in a polarity dependent manner, elevating or lowering neuron excitability in a region.	Sham Stimulation Sham stimulation sessions will be for 30 minutes daily for each of the 4 sessions; however, active stimulation for this arm of the study is only for 30 seconds; yet, will be applied at the same intensity as the Active arm of the study, albeit for only 30 seconds. Sham stimulation: Sham stimulation
