Summary

The purpose of this study is to determine whether "transcranial direct current stimulation" (tDCS) is effective in enhancing learning of complex motor tasks of precision and accuracy that require the simultaneous coordination of both hands. The study will utilize a between-subjects, SHAM controlled design. Subjects will be randomly selected to receive either SHAM (n=26) or a-tDCS (n=26) stimulation and will be blinded to their condition throughout testing. Subjects will complete a total of two testing sessions, separated by \~24 hours. Both sessions will have the subject play the videogame "Guitar Hero", with a single song done for several trials as pre- and post-assessments. The first session will contain a 20-minute practice/stimulation block where subjects practice the guitar task while receiving either "active" or "inactive" stimulation of the motor cortex. The first session will last approximately 75 to 90 minutes whereas the second session will last approximately 15 to 20 minutes.
