Blood oxygenation level-dependent contrast response functions identify mechanisms of covert attention in early visual areas
Covert attention can lead to improved performance in perceptual tasks. The neural and
functional mechanisms of covert attention are still under investigation. Using both rapid …

[HTML][HTML] Modelling contrast discrimination data suggest both the pedestal effect and stochastic resonance to be caused by the same mechanism
Computational models of spatial vision typically make use of a (rectified) linear filter, a
nonlinearity and dominant late noise to account for human contrast discrimination data …
