Special issue information:
The last decades have shown that the retina is much more than a simple camera or a bank of linear filters. While we know a lot about how the retina processes 'simple' artificial stimuli (e.g. full-field flicker or moving bars), much less is known about how it responds to more complex stimuli, and especially to natural scenes. Many studies have shown that complex stimuli are precisely the ones that will tap into the many non-linearities implemented by the retinal circuits, however, our understanding of non-linear processing in the retina is still limited. An assumption was that most forms of non-linear processing were only present in specific lower-vertebrate species, but several recent works have shown that complex processing also exists in the primate retina. In addition, large-scale recording techniques, particularly in combination with current computational modeling tools, offer to overcome a particular challenge in investigating natural vision, that is, efficiently probing the vast natural stimulus space. Our goal in this special issue is to bring together scientists from a wide range of disciplines to highlight the newest findings in retinal processing, and the most recent progress towards understanding non-linear processing in the retina. We hope to expand our understanding of how the retina processes complex natural stimuli, from the mechanisms to its impact of perception. Relevant topics include, but are not restricted to: Nonlinear processing of visual inputs, computational models of the retina, mechanisms of nonlinear processing, impact on perception, information transmission to retino-recipient regions of the brain, motion processing, color processing?
