Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The investigators will use magnetoencephalography (MEG) brain imaging to view the real-time effects of high definition (HD) tDCS on several brain areas involved in vision, hearing, movement, and memory. The investigators hypothesize that changing the task (auditory, visual or memory task) but keeping the position of the electrodes over the motor cortex will result in modulation of brain activity in only the central target motor area, and not on non-target temporal, occipital or pre-frontal areas.
