Effects of transcranial direct-current stimulation over the Supplementary Motor Area on motor control and inhibition

Summary

We are studying how a non-invasive, low electrical current applied through the scalp affects the part of the brain that helps start and stop movements. During one visit (about 1.5-2 hours) at Foothills Medical Centre, you will have a brain scan (MRI), receive 20 minutes of gentle transcranial direct-current stimulation (tDCS), and do simple computer button-press tasks. We will compare brain activity before, during, and after the stimulation. What we learn may help design future, non-invasive treatments for movement and tic disorders such as Tourette syndrome. Participants will receive $45 for their time.
