Abstract
What determines which motor units are active in a motor task? In the respiratory muscles, motor units are recruited according to their mechanical advantages. We describe a principle of motor unit recruitment by neuromechanical matching due to mechanisms in the spinal cord that sculpt descending drive to motoneurons. This principle may be applicable to movements in nonrespiratory muscles.
摘要
是什么决定了运动任务中哪些运动单位活跃？在呼吸肌中，运动单位根据其机械优势被募集。我们描述了一种由于脊髓中的机制来塑造向运动神经元的下行驱动，从而通过神经机械匹配来募集运动单位的原理。这个原理可能适用于非呼吸肌的运动。
