Abstract

Long-term recording from single lumbar motoneurons of intact cats revealed activation patterns fundamentally different from those seen in decerebrate preparations. In intact cats, motoneuron bursts showed marked rate modulation without initial doublets. Each unit's frequencygram generally resembled the envelope of the gross electromyogram simultaneously recorded from the corresponding muscle. Average and peak discharge rates increased for faster gaits. These findings suggest that, in cat locomotion, rate modulation is a more important contributor to force regulation than was previously thought.

摘要

对完整猫的单个腰段运动神经元进行长期记录发现,其激活模式与去大脑制备中观察到的模式根本不同。在完整猫中,运动神经元爆发显示出明显的频率调制,没有初始双峰。每个单位的频率图通常类似于同时从相应肌肉记录的肌电图的包络。更快步态时平均放电率和峰值放电率增加。这些发现表明,在猫的运动中,频率调制对力调节的贡献比以前认为的更为重要。
