As the old adage goes: practice makes perfect. Yet, the neural mechanisms by which rote repetition transforms a halting behavior into a fluid, effortless, and "automatic" action are not well understood. Here we consider the possibility that well-practiced motor sequences, which initially rely on higher-level decision-making circuits, become wholly specified in lower-level control circuits. We review studies informing this idea, discuss the constraints on such shift in control, and suggest approaches to pinpoint circuit-level changes associated with motor sequence learning.
熟能生巧。然而，我们对于重复练习是如何将一个生硬的行为转变为流畅、毫不费力且“自动化”的动作的神经机制还知之甚少。在这里，我们考虑了一种可能性，即经过充分练习的运动序列最初依赖于更高层次的决策回路，而最终完全由较低层次的控制回路来指定。我们回顾了支持这一观点的研究，并讨论了这种控制转变的限制，同时还提出了一些方法来确定与运动序列学习相关的回路水平变化。
