Abstract

Statistical dependence between parameters of hindlimb scratching movements and muscle electrical activity was studied in decerebrated cat during real scratching. Power of electrical signal to scratching and aiming muscles and duration of aiming muscle activity are determining factors of movement parameters (amplitude, velocity and phase duration). Experiments with limb deafferentation had shown that statistical dependences between movement parameters and muscle electrical activity reflect the peculiarities of the scratch generator functioning. Some investigated statistical dependences change under the afferent signal influence.

摘要

在去大脑猫进行真实抓挠时,研究了后肢抓挠运动参数与肌肉电活动之间的统计依赖性。电信号对抓挠肌和瞄准肌的功率以及瞄准肌活动的持续时间是运动参数(幅度、速度和相位持续时间)的决定因素。肢体去传入实验表明,运动参数与肌肉电活动之间的统计依赖性反映了抓挠发生器功能的特点。一些研究的统计依赖性在传入信号影响下会发生变化。
