The representation of the right hand in the sensory cortex of someone who reads Braille with their right hand would be larger compared to their left hand. This is because the sensory cortex's representation of body parts can change based on how much they are used, a phenomenon known as cortical plasticity. Reading Braille with the right hand significantly increases the use and sensory input from that hand, leading to an expanded representation in the sensory cortex.
