Stereopsis and binocular rivalry.
Stereopsis and binocular rivalry appear to be incompatible. Rivalry involves suppression of input from one eye at each location in space and time, whereas Stereopsis requires the combination of information from both eyes to yield a sensation of depth. This article presents a theory of the relationship of these phenomena. Evidence from previous work and from experiments reported here shows that ...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولHysteresis effects in stereopsis and binocular rivalry
Neural hysteresis plays a fundamental role in stereopsis and reveals the existence of positive feedback at the cortical level [Wilson, H. R., & Cowan, J. D. (1973). A mathematical theory of the functional dynamics of cortical and thalamic nervous tissue. Kybernetik 13(2), 55-80]. We measured hysteresis as a function of orientation disparity in tilted gratings in which a transition is perceived ...

15 صفحه اولA Model of Binocular Rivalry and Cross-orientation Suppression
Binocular rivalry and cross-orientation suppression are well-studied forms of competition in visual cortex, but models of these two types of competition are in tension with one another. Binocular rivalry occurs during the presentation of dichoptic grating stimuli, where two orthogonal gratings presented separately to the two eyes evoke strong alternations in perceptual dominance. Cross-orientat...
