Abstract
The role of tremor and drift in the formation of primary receptive fields a nd 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 cel ls 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 mechanophysica l processes whose mutual cooperation leads to the formation of the hysteres is signal informationally sufficient for monochrome and polychrome visual r ecognition.
