9:00 - 11:00 am – Invited Session #1: Gene and stem cell therapies for recovery of vision

The prospect of using genetic approaches to slow vision loss and restore visual function in blind individuals generates great excitement in the vision community, with the promise that major breakthroughs in treating blinding diseases may lie just ahead. The present symposium will discuss the most recent advances made in the field of gene therapy aimed at visual restoration. Speakers will detail successes achieved to date, our developing understanding of the constraints under which these therapies should be applied, work afoot to develop metrics for measuring effectiveness of these therapies, and generally, a discussion of what the future holds for the field.

3:30 - 5:30pm – Invited Session #2: Of mice and men: The rodent as a model system for vision

The mouse (and more generally the rodent) is increasingly being used as a model visual system. The use of the mouse offers advantages in terms of the increasing availability of advanced techniques for identifying, modifying, and manipulating specific neural types and neural circuits. This session will feature talks from scientists taking advantage of these techniques. At the same time, rodent vision may differ in important ways from human vision, so that some consideration of the generality of results obtained in mouse and rat is warranted. This session also has the goal of promoting discussion of this point.

9:00 - 11:00 am – Invited Session #3: Visual adaptation

Scientific study of visual adaptation has a long history, yet a deep understanding of adaptation mechanisms and, more importantly, its functional role(s) remains elusive. This session will bring together scientists who study visual adaptation using a broad range of approaches, including computation, neurophysiology and behavior. The goal of this session is to highlight recent advances in visual adaptation research and to facilitate discussion of common findings across a variety of approaches.

8:30 - 10:30am – Invited Session #4: Population coding in the visual pathways

As our models of the response properties of single neurons in the visual pathways has matured, there has been increasing interest in understanding the information carried, both implicitly and explicitly, by populations of neurons. This session will focus on research that seeks to measure and quantify how neural populations of neurons code visual information and will feature talks by investigators who employ a variety of techniques to study retina and cortex.

1:45 - 3:30pm – Invited Session #5: Mechanistic color psychophysics

     Moderator: David Brainard, University of Pennsylvania

The earliest methods of studying vision were psychophysical ones; for example, the trichromacy of human color vision was established pschophysically more than a century before the physiological underpinnings were identified. Vision science still needs psychophysics – to define the perceptual performance that is to be explained, to constrain neural models, and to guide physiologists and imagers in the choice and the control of stimuli. This session is devoted to current psychophysical work on color vision.
