为了达到一个意志目标，我们需要在特定的时间顺序中执行多个动作。在重复执行特定的动作序列后，我们能够在没有外部指导的情况下记住并执行整个序列。我们在大脑中的什么地方以及如何存储有序地执行多种运动所需的信息？我们在猴子的大脑皮层中发现了一组细胞，它们的活动只与以特定顺序进行的一系列多重运动有关。这种细胞活动存在于辅助运动区（1，2），但不存在于初级运动皮层（3，4）。我们认为，这些细胞有助于信号的顺序即将到来的多个运动，并有助于规划和编码的几个运动。
To achieve a volitional goal, we need to execute multiple movements in a specific temporal order. After repetitive performance of a particular sequence of movements, we are able to memorize and execute the whole sequence without external guidance. Where and how in the brain do we store information necessary for the orderly performance of multiple movements? We have found a group of cells in the cerebral cortex of monkeys whose activity is exclusively related to a sequence of multiple movements performed in a particular order. Such cellular activity exists in the supplementary motor area(1,2), but not in the primary motor cortex(3,4). We propose that these cells contribute a signal about the order of forthcoming multiple movements, and are useful for planning and coding of several movements ahead.
