运动系统通过组合简单的子运动来组成复杂的动作。这大概涉及到与控制另一个子运动的中心共享关于一个子运动的进展的信息，以确保第二个子运动与第一个子运动发生适当的关系。这个过程叫做协调。在本文中，我讨论的证据表明，协调行动确实涉及到一个积极的过程，分享信息的当前状态的运动。协调似乎与对外部刺激的反应过程有质的不同。这可能反映了预测表示在协调中的重要性。最后，协调的基础过程似乎是组织在一个响应特定的方式，作为一些相对独立的电路。这些回路的发展和调整，在某种程度上，可能是使一个动作“熟练”的原因。
The motor system composes complex actions by combining simpler submovements. This presumably involves sharing information about the progress of one submovement with the centres controlling another submovement, to ensure that the second happens in an appropriate relation to the first. This process is called coordination. In this paper I discuss evidence that coordinating actions indeed involves an active process of sharing information about the current state of movements. Coordination appears to be qualitatively different from the process of reacting to external stimuli. This may reflect the importance of predictive representations in coordination. Finally, the processes underlying coordination appear to be organized in a response-specific fashion, as a number of relatively independent circuits. The development and tuning of these circuits may, in part, be what makes an action "skilled".
