The experiment really rests on the following: What happens in the brain during something that's memorized and over-learned, and what happens in the brain during something that is spontaneously generated, or improvised, in a way that's matched motorically and in terms of lower-level sensory motor features?
Cosa succede nel cervello nel corso di qualcosa memorizzato e super-appreso, e cosa succede durante qualcosa spontaneamente generato, o improvvisato, ma che richiedono le stesse azioni motorie e processi sensoriali periferici?
