Final answer:
Krings et al. used fMRI to show that professional piano players have more brain activity than novices during piano playing, engaging multiple brain areas.
Step-by-step explanation:
Using fMRI, Krings et al. (2000) demonstrated that the brains of professional piano players were more active than novice players when making finger movements similar to those involved in playing the piano. Functional Magnetic Resonance Imaging (fMRI) generates a map of the most active areas of the brain during specific tasks by measuring changes in blood flow to the tissues. Unlike standard MRI, fMRI provides insights into the functionality of the brain during various tasks, showing that during complex activities, such as playing the piano, multiple brain areas, including visual sensory areas, integrating areas, and motor areas, are engaged, disproving the myth of using only 10% of our brain.
