我们回顾实验支持的假设，脊椎动物的运动系统产生的运动相结合的少量单位的电机输出。使用各种方法，如脊髓的微刺激，NMDA离子导入，并在完整的和去传入的动物的自然行为的检查，我们提供了脊髓的模块化组织的证据。模块是脊髓中的功能单元，其通过施加特定的肌肉激活模式来产生特定的运动输出。这样的组织可能有助于通过减少需要指定的自由度来简化运动的产生。(c)2007 Elsevier B.V.保留所有权利。
We review experiments supporting the hypothesis that the vertebrate motor system produces movements by combining a small number of units of motor output. Using a variety of approaches such as microstimulation of the spinal cord, NMDA iontophoresis, and an examination of natural behaviors in intact and deafferented animals we have provided evidence for a modular organization of the spinal cord. A module is a functional unit in the spinal cord that generates a specific motor output by imposing a specific pattern of muscle activation. Such an organization might help to simplify the production of movements by reducing the degrees of freedom that need to be specified. (c) 2007 Elsevier B.V. All rights reserved.
