Your friend is trying to teach you how to play guitar. You've taken a few lessons with them already and they are now trying to show you how to play a new chord. You watch them play the chord a few times before picking up your own guitar and trying it yourself. You strum the strings with your right hand, meaning you use the fingers on your left hand to manipulate the strings on the guitar neck (which requires more control than what your strumming hand is doing). Assuming that you continue practicing your guitar playing, what change in your brain could be predicted?
A)a smaller left-hemisphere somatosensory cortex
B)a larger left-hemisphere somatosensory cortex
C)a larger right-hemisphere somatosensory cortex
D)a smaller right-hemisphere somatosensory cortex
E)none of these possible responses would be predicted.

Practicing guitar involves fine motor skills and sensory feedback, which can lead to an increase in the size of the right-hemisphere somatosensory cortex, as it controls the left hand.
