Our research is dedicated to uncovering the neural circuits and neural mechanisms underlying visual perception and visual processing. Using voltage-sensitive dye imaging and additional cutting-edge technologies we aim at decoding and reconstruction of visual content from brain activity of behaving animals. We investigate artificial vision in the primary visual cortex using electrical microstimulation and optostimulation of neuronal population.  

Our long-term goals are to provide novel insights into perceptually guided behavior, facilitate the development of a useful cortical visual neuroprosthesis, and improve the treatment of visually impaired subjects.

A new lab. paper 🎯 📢 with Dr. Shany Nivinsky Margalit 🏆: Encoding luminance surfaces in the visual cortex of mice and monkeys: difference in responses to edge and center.
In this work, we investigated the neural responses to luminance surfaces in the primary visual cortex of both mice and monkeys. Because mice have low visual acuity and lack a fovea, which differs from monkeys, it is unclear whether they share similar neural mechanisms to process surfaces. We found that in mice, the population response to the surface was not edge-dominated with a tendency to center dominance, whereas, in monkeys, the response was edge-dominated with a “hole” in the center of the surface. This is summarized in the visual abstract below.
