Magnetic source imaging revealed that the cortical representation of the digits of the left hand of string players was larger than that in controls. The effect was smallest for the left thumb, and no such differences were observed for the representations of the right hand digits. The amount of cortical reorganization in the representation of the fingering digits was correlated with the age at which the person had begun to play. These results suggest that the representation of different parts of the body in the primary somatosensory cortex of humans depends on use and changes to conform to the current needs and experiences of the individual.
磁源成像显示，弦乐器演奏者左手手指的皮质表征比对照组更大。这种效应在左手拇指上最小，而右手手指的表征则未观察到此类差异。手指弹奏部位的皮质重组程度与个体开始演奏的年龄相关。这些结果表明，人类初级体感皮层中身体不同部位的表征取决于使用情况，并会发生变化以符合个体当前的需求和体验。
