The role of tremor and drift in the formation of primary receptive fields and signals of space-frequency transformations at the level of retina fovea centralies cells was investigated. The mechanism of organization of direct informational connection between photoreceptors, horizontal and bipolar cells was determined, and the formulas for the synthesis of visual information signals were derived taking into account the frequency of participation of image elements. It is shown that tremor and drift are those mechanophysical processes whose mutual cooperation leads to the formation of the hysteresis signal informationally sufficient for monochrome and polychrome visual recognition.
研究了震颤和漂移在视网膜中央凹细胞水平上初级感受野形成以及空间频率变换信号中的作用。确定了光感受器、水平细胞和双极细胞之间直接信息连接的组织机制,并考虑图像元素参与频率推导出视觉信息信号合成公式。结果表明,震颤和漂移是机械物理过程,它们的相互协作导致形成对单色和多色视觉识别在信息上足够的滞后信号。
