A conditioned food-procuring reflex to time (2-min interval) was developed in cats. The coupled activity of neurons in microareas and between microareas of the motor cortex was compared by cross correlation analysis in different forms of the manifestations of the conditioned reflex: decrease in the amplitude of respiratory movements, increase in amplitude, and food-procuring movement of the paw for several seconds prior to the delivery of the reinforcement. Differences were manifested in the degree of increase in the number of functional associations in the second half of the interval as compared with the first, and, to a still greater degree, also in the frequency with which intervals were encountered with altered structure of the interrelationship between the neurons. The changes observed did not always correlate with the change in the frequency of impulse activity of individual neurons, which was noted substantially less frequently.
在猫身上建立了对时间（2分钟间隔）的条件性获取食物反射。通过交叉相关分析，比较了在条件反射不同表现形式下，运动皮层微区内部和微区之间神经元的耦合活动：呼吸运动幅度降低、幅度增加以及在给予强化物前几秒钟爪子的获取食物运动。与前半段间隔相比，后半段间隔中功能关联数量增加的程度存在差异，并且在神经元间相互关系结构改变的间隔出现频率方面差异更大。观察到的这些变化并不总是与单个神经元冲动活动频率的变化相关，而单个神经元冲动活动频率的变化要少得多。
