Topic: BOS neurons

To make sense of visual scenes, the brain must segment objects from background. This is thought to be facilitated by border ownership (BOS) neurons in the primate visual cortex. These neurons encode whether a local border in a visual scene is part of an object on one or the other side of the border. It is unclear how these signals emerge in neural networks without a teaching signal of what is foreground and what is background. Here we discovered that brain-like BOS units emerge in PredNet, a deep artificial neural network that is not trained to segment objects but simply to predict future fram
