Despite substantial advances in the field, particularly resulting from physiological studies in animals, the neural mechanisms underlying the generation of many motor behaviors in humans remain unclear. A recent study (Cappellini G et al. J Neurophysiol 104: 3064-3073, 2010) sheds more light on this topic. Like the string of a violin, the α-motoneuron pools in the spinal cord during locomotion show continuous and oscillatory patterns of activation. In this report, the implications and relevance of this finding are discussed in a general framework that includes neurophysiology, optimal control theory, and robotics.
尽管该领域取得了重大进展，特别是动物生理学研究取得了重大进展，但人类许多运动行为的产生的神经机制仍不清楚。最近的一项研究（Cappellini G 等人，《神经生理学杂志》104:3064-3073，2010）进一步阐明了这一主题。就像小提琴的琴弦一样，运动时脊髓中的α运动神经元池表现出连续的和振荡的激活模式。在本报告中，该发现的意义和相关性在包括神经生理学、最优控制理论和机器人学在内的一般框架中进行了讨论。
