运动神经元活动模式能在多大程度上解释行为？有多少行为是由“中心模式”产生的，有多少取决于系统的机制？运动模式在多大程度上反映了肌肉特性及其排列对神经系统施加的机械需求？为了解决这类问题，我们已经开始开发水蛭的生物力学模型（Skalak et al. 1996），该模型基于水蛭的身体结构、肌肉的机械特性以及神经信号到肌肉激活的转化。这些特性是神经肌肉系统的任何生物力学描述所需的标准特性，但由于水蛭和许多其他无脊椎动物一样，没有刚性的骨骼（无论是内部还是外部）来产生运动，这一事实使这项工作变得复杂。水蛭的肌肉必须使作为骨骼的整个或部分身体变得僵硬。
How well can patterns of motor neuronal activity account for behavior? How much of the behavior is produced by “central patterns” and how much depends on the mechanics of the system? To what extent do motor patterns reflect mechanical necessities imposed on the nervous system by the properties of muscles and their arrangements? To approach these kinds of questions, we have started to develop a biomechanical model of the leech (Skalak et al. 1996), based on the structure of the leech body, the mechanical properties of their muscles, and the transformation of neural signals into activation of the muscles. These properties are the standard ones needed for any biomechanical description of a neuromuscular system, but this effort is complicated by the fact that leeches, like many other invertebrate animals, have no rigid skeleton—either internally or externally—with which to produce movements. Leech muscles must stiffen all or part of its body that serves as a skeleton.
