Recent research suggests that the nervous system controls muscles by activating flexible combinations of muscle synergies to produce a wide repertoire of movements. Muscle synergies are like building blocks, defining characteristic patterns of activation across multiple muscles that may be unique to each individual, but perform similar functions. The identification of muscle synergies has strong implications for the organization and structure of the nervous system, providing a mechanism by which task-level motor intentions are translated into detailed, low-level muscle activation patterns. Understanding the complex interplay between neural circuits and biomechanics that give rise to muscle synergies will be crucial to advancing our understanding of neural control mechanisms for movement.
最近的研究表明，神经系统通过激活肌肉协同作用的灵活组合来控制肌肉，从而产生各种各样的运动。肌肉协同作用就像积木一样，定义了多个肌肉的特征性激活模式，这些模式可能因人而异，但执行类似的功能。肌肉协同作用的识别对神经系统的组织和结构具有重要意义，它提供了一种机制，通过该机制任务级别的运动意图被转化为详细的、低级别的肌肉激活模式。理解产生肌肉协同作用的神经回路与生物力学之间的复杂相互作用，对于推进我们对运动神经控制机制的理解至关重要。
