Spike activity of unitary motor cortex (area 4) neurons was recorded during performance of conditioned reflex postural adjustment in cats. Changes in activity of most neurons (increase of discharge frequency) correlated with conditioned-reflex supporting movement of the forelimb. These neuronal reactions had specific polycomponent patterns and preceded the conditional movements by 50-600 ms. Neuronal reactions connected with erroneous positive movement responses to differential stimuli and spontaneous "interstimular" movements had the same direction but were less intensive and occurred in most cases synchronously with these movements. Neuronal reactions and postural adjustments simultaneously disappeared during reflex extinction. The proposed method of elaboration of conditioned reflex of postural adjustments permits obtaining standard natural coordinated forelimb movements which form the necessary initial component of more complex behavioral reactions.
在猫进行条件反射性姿势调整的过程中，记录了单一运动皮层（4区）神经元的锋电位活动。大多数神经元活动的变化（放电频率增加）与支持前肢的条件反射性运动相关。这些神经元反应具有特定的多成分模式，并在条件性运动之前50 - 600毫秒出现。与对差异刺激的错误阳性运动反应和自发的“刺激间隙”运动相关的神经元反应方向相同，但强度较小，且在大多数情况下与这些运动同步发生。在反射消退期间，神经元反应和姿势调整同时消失。所提出的构建姿势调整条件反射的方法能够获得标准的自然协调前肢运动，这些运动构成了更复杂行为反应的必要初始成分。
