Wyeth Bair, University of Washington, aims to understand neural circuitry and neural coding in the cerebral cortex of the primate visual system. He approaches this problem by recording directly from neurons in the functioning brain in vivo and by creating and refining large scale spiking neural network models that run on parallel computers (see http://www.imodel.org).

James Bisley, University of California, Los Angeles

Jan Brascamp, Michigan State University, studies the neural processes of interpretation and selection that allow sensation (the retinas detecting light) to turn into conscious visual perception (seeing). He investigates these processes by presenting observers with ambiguous or conflicting visual input. This approach provides an exceptional window into the visual system trying creating a perceptual interpretation based on sensory input and, indeed, switching between interpretations over time even though the input stays the same.

Anitha Pasupathy, University of Washington ,works on the neural basis of visual shape perception and recognition, the ability to identify and recognize objects from all angles, distances, and in almost any lighting condition. She uses single cell neurophysiological studies in awake monkeys, behavioral manipulations, computational modeling and reversible inactivation techniques to investigate how the information reaching our eyes is represented in the neural activity patterns in the brain, how these representations are transformed in successive stages and finally how these representations inform behavior.
