In kittens of the age from 39 days to 4 months the influence was studied of the sensorimotor cortex (SMC) ablation on formation and preservation of previously elaborated reflex to a simultaneous complex stimulus (light + sound) with extinction of reaction to nonreinforced components of the complex signal. It is shown that SMC ablation in the age up to 2.5 months does not affect the formation or preservation of the conditioned reflex. The SMC ablation in preliminarily trained kittens in the age of 3.5 months and older leads to disinhibition of components differentiation with preservation of the positive conditioned reflex to the complex signal. In untrained kittens of the same age the SMC ablation leads to disability of animals to inhibit the motor reaction to differentiation signal. The question is discussed of SMC significance in the ontogenesis at formation of adequate forms of behaviour requiring heterosensory interaction.
在39日龄至4月龄的小猫中，研究了感觉运动皮层（SMC）切除对先前形成的对同时复合刺激（光 + 声）的反射的形成和保持的影响，以及对复合信号非强化成分反应的消退情况。结果表明，在2.5月龄之前切除SMC不会影响条件反射的形成或保持。在3.5月龄及以上的预先训练过的小猫中切除SMC会导致成分分化的去抑制，同时对复合信号保持阳性条件反射。在相同年龄的未训练小猫中，切除SMC会导致动物无法抑制对分化信号的运动反应。讨论了SMC在个体发育过程中对需要异感觉相互作用的适当行为形式形成的意义问题。
