The effect of sequential applications of the weak anode DC (0.5-3 mcA) to the areas of fore- and hindlimb representation in the motor cortex was studied in waking unrestrained rabbits. This procedure formed two excitation foci with the dominant properties, i.e., different afferent stimuli (sound, light) produced the dominant behavioral reaction (limb movement). The cooperative inhibition of the dominant foci was observed in the process of formation of the second focus in different time intervals. The second focus inhibited the primary focus for a rather long-term period, and then the mutual inhibition of the foci acquired the reciprocal character. The obtained results testify to excitation redistribution in the motor cortex during the action of weak anode DC on the motor cortex.
在清醒无拘束的家兔身上，研究了在运动皮层前肢和后肢代表区依次施加弱阳极直流电（0.5 - 3毫安）的效果。这一过程形成了两个具有主导特性的兴奋灶，即不同的传入刺激（声音、光线）会引发主导行为反应（肢体运动）。在不同时间间隔形成第二个兴奋灶的过程中，观察到了主导兴奋灶的协同抑制现象。第二个兴奋灶在相当长的一段时间内抑制了初级兴奋灶，随后兴奋灶之间的相互抑制呈现出相互作用的特征。所获结果证明，在弱阳极直流电作用于运动皮层时，运动皮层会发生兴奋重新分布。
