How do we visually segregate objects from other objects and the background?
In a recent article, we show that the representation of object borders is enhanced in the early visual cortex (V1). Moreover, V1 neurons discriminate perceptually relevant object borders surprisingly fast, i.e., during the early feedforward-driven activity at a latency of ~50 ms. We also revealed a delayed, contextual effect that enhances the V1 responses that are elicited by perceptually relevant borders at a longer latency. Our results reveal multiple mechanisms that allow early visual cortex to infer the layout of objects in natural images.
