In acute experiments on unanaesthetized cats immobilized with listenon, a study was made ofthe variability and interdependence of evoked responses to photic stimulation in the thalamo-cortical formations of the visual projection and the associative systems: the lateral geniculate body, pulvinar and the visual and parietal associative areas of the cerebral cortex. It has been shown that the variation coefficient of the amplitude from the maximum of the positive to the maximum of the negative oscillations in the parietal cortex statistically significantly exceeds the one in the lateral geniculate body and the projection cortex. Coefficients of paired correlation of evoked potentials' amplitudes to light more frequently reach significant levels for pairs consisting of one level formations, cortical or thalamic, than for pairs including formations of different levels.
在用箭毒固定的未麻醉猫身上进行的急性实验中，研究了视觉投射和联合系统的丘脑 - 皮质结构中对光刺激诱发反应的变异性和相互依赖性，这些结构包括外侧膝状体、丘脑枕以及大脑皮质的视觉和顶叶联合区。结果表明，顶叶皮质中从正振荡最大值到负振荡最大值的振幅变异系数在统计学上显著超过外侧膝状体和投射皮质中的变异系数。诱发电位振幅与光的配对相关系数，对于由皮质或丘脑的同一水平结构组成的配对，比对于包括不同水平结构的配对更频繁地达到显著水平。
