Sergei Gepshtein


Director
Collaboratory for Adaptive Sensory Technologies
As the founding director of the Collaboratory for Adaptive Sensory Technologies at the Salk Institute, Sergei Gepshtein studies visual perception and visually guided behavior using methods of sensorimotor psychophysics and computational neuroscience. One of Sergei’s long-standing interests is the interaction between two aspects of visual perception: the entry process called early vision and the constructive process called perceptual organization. Early vision captures visual information and thus determines the boundaries between the visible and invisible. Perceptual organization creates visual meaning; it constructs our visual experience (the “visual world”) from the information captured by early vision.
