Modulation of Motor Learning Via tDCS in a Dexterous Video Game Task
Stopped early · Not applicable · Has a placebo group
Conditions studied: Motor Activity
In brief
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.

Who can join
Age: 18 and older, up to 45. Sex: any. Healthy volunteers: accepted.
You may qualify if…
- Between ages 18 and 45 years old (to avoid any changes in the developing brain, or with aging).
- Answer 'no' to questions 2 through 16 on the tDCS checklist as these factors can increase likelihood of adverse events with tDCS
- No neurological damage, disease, or dysfunction (nerve damage, chronic pain disorders, diabetic neuropathy) that affect the upper limbs.
- No significant acute or chronic medical, neurologic, or illness in the patient that, in the judgment of the Principal Investigator, could compromise subject safety, limit the ability to complete the study, and/or compromise the objectives of the study
You may not qualify if…
- • Currently prescribed and taking stimulant medication (Adderall, Ritalin, Vyvanse, etc.)
- Consumption of over-the-counter stimulants such as caffeine or nicotine (coffee, soda, supplements, energy drinks, tobacco products, or other nicotine containing products such as gum, vape pens, etc...) 12 hours prior to entering the lab on the day of testing as this can directly affect cortical excitability. If a subject takes any of these substances 12 hours prior to session 1 they will be asked to reschedule for a later date.
- Have played a real stringed instrument in the last 12 months (e.g. guitar, bass, violin)
- Have played the videogame "Guitar Hero" on a traditional guitar controller in the last 12 months.
