Summary

The long-term objective initiated with this study is to determine which brain areas functionally contribute to learning a motor skill. The primary hypothesis of this trial is that premotor cortex (PMC) is necessary to learn a new motor skill. Participants may undergo a MRI scan to acquire a structural image of their brain to target noninvasive stimulation, using transcranial magnetic stimulation (TMS) to one of two brain areas: PMC or primary motor cortex (M1). A third group of individuals will undergo a placebo stimulation protocol. For all three groups, stimulation will be used to create a transient 'virtual lesion' during motor skill training. Temporarily disrupting the normal activity of these brain regions during training will allow us to determine which regions are causally involved in learning a new motor skill. The primary outcome measure will be the change in skill after training in each group.

DEVICE

Transcranial Magnetic Stimulation (TMS)

Transcranial magnetic stimulation, also known as repetitive transcranial magnetic stimulation, is a noninvasive form of brain stimulation in which a changing magnetic field is used to cause electric current at a specific area of the brain through electromagnetic induction. It will be used to create a 'virtual lesion,' disrupting neural activity in a specific brain region to identify whether it is causally involved in a specific behavioral process.
