We used a computational analysis to identify the basic elements with which the vertebrate spinal cord constructs one complex behavior. This analysis extracted a small set of muscle synergies from the range of muscle activations generated by cutaneous stimulation of the frog hindlimb. The flexible combination of these synergies was able to account for the large number of different motor patterns produced by different animals. These results therefore demonstrate one strategy used by the vertebrate nervous system to produce movement in a computationally simple manner.
我们采用了一种计算分析方法来识别脊椎动物脊髓构建一种复杂行为所使用的基本要素。该分析从青蛙后肢皮肤刺激所产生的肌肉激活范围内提取了一小组肌肉协同作用。这些协同作用的灵活组合能够解释不同动物产生的大量不同运动模式。因此，这些结果证明了脊椎动物神经系统以计算简单的方式产生运动所采用的一种策略。
