Foveal vision in amblyopia.
THE reduced visual acuity in amblyopic eyes has presented a.problem ever since the condition was recognized. Most of the evidence so far favours the cortex as the site of inhibition (Vogt, 1939; Wald and Burian, 1944; Dyer and Bierman, 1952). Clarke (1941) thought that the cause might be an atrophy from disuse affecting the cells of the lateral geniculate body which rely for their vitality on t...
متن کاملDiscriminating mirror symmetry in foveal and extra-foveal vision
The ability to discriminate perfect from imperfect mirror symmetry was examined at the fovea and at eccentricities out to 10 degrees in the nasal visual field. A 2-AFC method of constant stimuli was employed in which a bilaterally symmetric pattern was presented in one interval and a degraded version of this symmetric pattern in the other. The subject's task was to decide which interval contain...
متن کاملModeling Foveal Vision
A geometric model is proposed for an artificial foveal vision system, and its plausibility in the context of biological vision is explored. The model is based on an isotropic, scale invariant two-form that describes the spatial layout of receptive fields in the the visual sensorium (in the biological context roughly corresponding to retina, LGN, and V1). It overcomes the limitation of the famil...
متن کاملEye movements and the after-image. II. The effect of foveal and non-foveal after-images on saccadic behaviour.
Fovea1 and non-fovea1 after-images affect saccadic behaviour in different ways.Fovea1 after-images inhibit saccades and facilitate smooth eye movements whether or notinstructions to track the after-image are given. Parafoveal after-images are effective stimulifor eliciting consistent eye movement patterns, but these patterns change when instructions aregiven. Peripheral after-im...
متن کاملOrientation discrimination in foveal and extra-foveal vision: effects of stimulus bandwidth and contrast
The parameter E2 is used in many spatial scaling studies to characterize the rate at which stimulus size must increase with eccentricity to achieve foveal levels of performance in detection and discrimination tasks. We examined whether the E2 for an orientation discrimination task was dependent on the spatial frequency bandwidth of the stimulus used. Two methods were employed. In Experiments 1 ...
