    “The impact of eye-movements on neural dynamics and cortical organization”

    Dr. Nandy has a broad background in signal processing, psychophysics and computational modeling from pre-doctoral and doctoral work. His doctoral research resulted in the first comprehensive model of visual crowding, a ubiquitous phenomenon in peripheral vision that severely degrades our ability to identify objects in clutter. Crowding is especially detrimental in patients with central vision loss. He also demonstrated that the oculomotor system has a remarkable ability to rapidly and persistently adapt to simulated central vision loss in normally sighted human subjects. During his post-doctoral training at the Salk Institute, he employed advanced electrophysiological and optogenetic techniques in the alert non-human primate to investigate the neuronal mechanisms of shape processing and attention in the visual cortex. His research has uncovered the detailed spatio-temporal structure of shape processing in neurons in visual area V4, a critical area for both shape processing and attention. His results force him to reconsider the established notion that neuronal invariance increases as one traverses the cortical hierarchy. He has investigated the causal role of low-frequency correlated variability in neural activity on attentive behavior. Further, he has uncovered the cortical layer-specific organization of attentional modulation in the visual cortex. Together, these studies promise to significantly advance our current understanding of the cortical circuits of attention.
