Main point:

In an experiment electroencephalography (EEG) was used to study cortical activity during preparation for movement in experienced and novice guitarists. In the brains of experienced players less cortial activity occurs. Authors say: “motor preparation of experts is more efficient than that of novices.”

My thoughts: Isn’t it the same experiment that they report here?
