rTMS Induced Reduction in M1 Excitability

When learning a new skill, much of the improvement comes from small alterations the brain makes with each repetition during practice, but this isn\'t the only time that improvements are made during the learning process. Individuals also get better at the motor skills during the time between practices, through a process called \"consolidation.\" It is known that an area of the brain called the primary motor cortex is involved in learning during active practice, but the investigators want to study if the primary motor cortex is important for consolidation. The investigators will examine how lowering the activity in this brain region affects your ability to consolidate learning to play a song on the videogame Guitar Hero.
