Perception of stabilized retinal stimuli was studied both in monocular and dichoptic viewing conditions. When identical stabilized stimuli of large size and high luminance were presented to both eyes, the phenomena characteristic of monocular perception (rapid fading of perceived images within a few seconds or their episodic disappearance and regeneration)(More)
Accurate measurements of uncorrected binocular and monocular visual acuity were performed in 65 children aged 5-7 years at five viewing distances in the range 0.5-5.0 m by means of the test charts containing widely spaced E stimuli in four orientations. It was found that, in most children of this age, visual acuity (V) changed with test distance, as had(More)
The giant interneurons in the terminal abdominal ganglion of cricket (Acheta domesticus) were studied using sound signals with special interest to the effect of the body tilt on the directional sensitivity diagrams. The neurons under study receive their inputs from the cerci which have receptors sensitive to mechanic and acoustic stimulation and receptors(More)
The influence of monocular spatial cues on the vergence eye movements was studied in two series of experiments: (I) the subjects were viewing a 3-D video and also its 2-D version-binocularly and monocularly; and (II) in binocular and monocular viewing conditions, the subjects were presented with stationary 2-D stimuli containing or not containing some(More)
A thorough analysis of the literature on retinal image stabilization, as well as our own experimental data, present evidence that Yarbus's concept, implying inevitable and irreversible fading of a visible image evoked by stabilized retinal stimulus of any size, color, and luminance in 1 to 3 s after its onset, is not valid in a general case. It has been(More)
A method of assessing fusional reserves using an interactive computer program, which allows to monitor the subjects report on the moment of fusion break with artificial increase of convergence or divergence of the vii sual axes in the measurement process was developed and tested. Control is achieved through the use of a purely binocular stimuli--random-dot(More)
Stimulation with linearly changing signals was used to study identified neurons 10-3a and 9-lb of the cereal system of the cricket with the aim of identifying which parameter of the wind stimulus (speed, acceleration, etc.) determined their responses. The results showed that the factor affecting neuron 10-3a was acceleration of the airflow, wile the(More)
When a mobile device (notebook, smartphone, etc.) is used, the images on the monitor screen may be significantly distorted by a strong external light (for instance, sunlight) illuminating the screen surface. This additional illumination reduces all the local contrast values in the displayed images and leads to fading and deterioration of the subjective(More)
Application interactive CLASS software for stimulating productive binocular cooperation based on random-dot patterns and stereograms was used for treating strabismus and amblyopia in 105 children during a standard course of treatment. The children were divided into 3 groups treated by the CLASS alone (1), Class + two other application programs (2), and(More)
Model of signal processing in mechano-acoustical cercal system of insects is described in which the invariance of the perceived signal direction with respect to the positions of sense organs (cerci) is achieved due to connections of four central neurons with certain receptor groups on both cerci. The data published earlier suggest that the monocercal(More)
