And so 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?
实验其实是由以下的内容组成的。 大脑在人们靠记忆演奏熟知的音乐时是怎样反应的？ 大脑在演奏者自发和即兴创作 时又是如何反应的？ 从某个角度来说这与肌肉运动相匹配 并符合低级感知运动的特征吗？
