[A model of the neuronal network using eye micromovements for distinguishing contrasts on an image].
A monochromatic model of a neuron network of foveal retina with the straight way of information stream of the system "cone-diminutive bipolar-diminutive ganglion cell" is proposed. The network can distinguish contrasts on an image. It is shown that cells of the output level have concentric receptive fields formed due to eye micromovements. The paper discusses the functioning of the model in the case when eye movements contain resetting microsaccades as well as drift. A special attention is paid to the compensation of transient processes.

[The role of tracking in the perception of objects, moving toward each other in a narrow vertical slit line].
It has been shown by means of calculation and device modeling that the observed subjective pressure of two objects moving toward one another behind a narrow vertical slit corresponds to the pressure of objects retinal projections, induced in its turn by a slowed down tracing. 180e turn of one of the moving objects is also explained by tracing.
Form Perception↗
[Perception of objects, moving in a slit with random shape].
By means of calculation and instrumental modeling it has been shown that a change of the form and slurring of the object moving in a slit of an arbitrary shape results from a distortion of the retinal projection appearing due to decelerated following.

[Subjective compression of an object moving in the line of the rangefinder].
It has been shown by recording eye movements and objective estimation that the value of subjective pressure of the object corresponds to the pressure of its retinal projection, which in its turn is determined by delayed tracing. Dependence of the value of relative subjective pressure on the slit width is determined at three values of the velocity of object movement.

[Tracing eye movements in various types of stroboscopic stimulation].
Relationship between eye ability to perceive smooth motion under stroboscopic stimulation on forward motion (from which stationary positions of the object) in the plane perpendicular to the look line was found. For diagnostics and occupational selection it is suggested to carry out stimulation in several directions thus obtaining additional information about the visual system of the person under test.

[A neuronal network model, discerning faint image contours in the presence of primary receptor parameter scatter].
The neuron network model reproducing a number of phenomena concerned with peculiarities of monocular vision of moving and stationary relative to the retina objects was investigated. An analysis has shown that fulfillment of additional requirement of remaining model efficiency under condition of primary receptors parameters scatter may be realised in aforesaid model by insignificant modification of network structure.

[Computer modeling of the neural network recognizing the contrasts on the image].
Computer modeling of the neuron network offered in [1] is discussed. Organization and feature of modeling are described, as well as the changes, which are introduced in the network during researches. Results of modeling are present.
