Modeling Disinhibition in the Early Visual Pathway
نویسندگان
چکیده
Conventional Difference of Gaussians (DoG) filter is usually used to model the early stage of visual processing. However, the convolution operation used with DoG does not explicitly account for the effects of disinhibition. Because of this, complex brightness contrast illusions such as the White effect cannot be explained using DoG filters. We discovered that a new model explicitly accounting for disinhibition allows us to explain why these brightness contrast illusions arise, and show that a feedforward filter can be derived to achieve this in a single pass.

A Neural Model of the Scintillating Grid Illusion: Disinhibition and Self-Inhibition in Early Vision
A stationary display of white discs positioned on intersecting gray bars on a dark background gives rise to a striking scintillating effect--the scintillating grid illusion. The spatial and temporal properties of the illusion are well known, but a neuronal-level explanation of the mechanism has not been fully investigated. Motivated by the neurophysiology of the Limulus retina, we propose disin...
متن کاملHow visual stimuli activate dopaminergic neurons at short latency.
Unexpected, biologically salient stimuli elicit a short-latency, phasic response in midbrain dopaminergic (DA) neurons. Although this signal is important for reinforcement learning, the information it conveys to forebrain target structures remains uncertain. One way to decode the phasic DA signal would be to determine the perceptual properties of sensory inputs to DA neurons. After local disinh...

متن کاملAngular Disinhibition Effect in a Modified Poggendorff Illusion
Visual illusion can be strengthened or weakened with the addition of extra visual elements. For example, in Poggendorff illusion, with an additional bar added, the illusory skew in the perceived angle can be enlarged or reduced. In this paper, we show that a nontrivial interaction between lateral inhibitory processes in the early visual system (i.e., disinhibition) can explain such enhancement ...
متن کاملParsing the Undercontrol/Disinhibition Pathway to Substance Use Disorders: A Multilevel Developmental Problem.
A long-standing and diverse body of evidence has documented the importance of externalizing characteristics as very early etiologic predictors of a pathway to severe alcohol and other drug problems and substance use disorder. At the same time, much remains unclear about the mechanistic structure of this pathway, including understanding what the defining characteristics are that encompass the di...
