Abstract

The control processes caused by the action of electric inhibition of the nerve fibres and depolarized and hyperpolarized influences in the neurones structures of the spinal cord are discussed. Three typical bands of the amplitude control of motor apparatus in the multineuronic reflex ring are distinguished. The transmission of the action potentials in the battle control bands is carried out by the double way modulation. The first band is characterized by the most effective control with amplitude of the signal control in the limit of three thresholds. In the third band the transmission of information is possible in the inversion regime with unsteady polarity of the reflex movement. The second band unfits for the transmission of control commands.

摘要

讨论了由神经纤维电抑制作用以及脊髓神经元结构中的去极化和超极化影响所引起的控制过程。区分了多神经元反射环中运动装置幅度控制的三个典型频段。战斗控制频段中动作电位的传递通过双向调制进行。第一个频段的特征是在三个阈值范围内对信号控制幅度进行最有效的控制。在第三个频段中,信息可以在反射运动极性不稳定的反转状态下传递。第二个频段不适合传递控制指令。
