8:15-10:10 Invited session: 30 years of normalization in the visual system 

The modern view of neuronal normalization dates back to the late 80s and early 90s and in particular, to a paper published in 1992 by David Heeger entitled "Normalization of Cell Responses in Cat Visual Cortex" in which a single, elegant model of contrast gain control was shown to explain much of the then current literature on early visual processing. Thirty years later, normalization appears to be one of a set of fundamental 'canonical computations' that can used to explain how the brain works. This session features four speakers who have used neuronal normalization to explain different aspects of vision in a modern context including binocular combination, attention and adaptation.

13:15–15:10 Invited session: Retinal remodeling and regeneration

Regenerative therapies aim to restore light sensitivity to blind retina or prevent further vision loss by replacing compromised or degenerated retinal tissues with new healthy cells. While these approaches have the potential to deliver high quality restored vision they must also contend with anatomical and physiological changes that occur in the remaining retinal architecture after vision loss. This session will cover the latest advances in cell transplantation & regeneration and consider how native retinal circuits adapt and remodel in the face of retinal degeneration.

Computational modeling of vision: Ten lessons
Computational models are the means by which we test our ideas about how vision works. They have well-defined inputs, that bear some defined relation to the light impinging on the eyes. And they have well defined quantitative outputs, that relate to human judgements. Their success can be judged by how well they predict those human judgements, by how broad the range of conditions they encompass, and possibly by how well their internals match the neurophysiology. Tangentially, they may be judged by how useful they are in practical applications. In this talk I will share a few lessons that I have learned from my adventures in modeling of human vision.

8:00-9:55 Invited session: Diversity in chromatic processing across the animal kingdom 

Color is an important feature of objects in the visual environment. While the neural transformations underlying color perception have received much attention in the primate visual system, the broader animal kingdom exhibits a diverse set of schemes for encoding and processing chromatic information. This session will survey the neural organization of color pathways in a selection of primate and non-primate species, and will examine how those pathways can be used to extract ecologically-relevant signals that guide behavior.

Wiring specificity and plasticity of the vertebrate retina
Vision relies on the output of the many functionally distinct and precisely wired circuits of the retina. Using transgenic techniques, imaging methods and electrophysiology, we seek to uncover the developmental mechanisms that help establish the wiring specificity of retinal circuits in vertebrates. Moreover, because injury or disease can cause rewiring after maturation, we are also reconstructing primate retinal circuits impacted by the loss of input, in order to identify the challenges to circuit repair.

8:00-9:55 Invited session: Binocular vision & interactions

Binocular vision shapes our ability to perceive and act on our environments, guiding our visuomotor interactions with the objects around us. Speakers in this session will discuss how stereo vision and 3D perception guide movement and support our ability to interact with the world, and how we can use clinical applications and augmented/virtual reality approaches to understand how the human visual system processes depth information under typical and atypical conditions.
