Across the primate neocortex, neurons dedicated to similar functions are likely to be found physically nearby. In the high-level visual cortex, this principle gives rise to cortical patches with distinct category selectivity that were previously observed across many species including macaque monkeys and humans. Models of visual cortex based on artificial neural networks (ANN) have been shown to contain internal representations that are remarkably similar to those observed in the visual cortex. However, unit selectivity in these models emerges without any particular spatial order (i.e. no topog
