Question

Quizplus · Accepted Answer

Since Devin is left-handed and has been playing the electric guitar for almost 20 years, he has likely developed increased motor skills in his left hand. This increase in skill is likely due to changes in the motor cortex in the left hemisphere of his brain, specifically in the hand region. Therefore, an MRI scan of Devin's brain would likely show an increase in the size of the hand region in motor cortex in the left hemisphere.
