Resolving border disputes in midlevel vision.
Two papers in this issue of Neuron specify the coding of border ownership, the basis of figure-ground segmentation, in early extrastriate visual cortex (area V2). Recording from a population of neurons, Qiu and von der Heydt show that border ownership assignments based on 2D images show the same bias when tested with stereopsis. Zhaoping shows that a neural model of V2 can make appropriate border assignments based on 2D images.
