Left: conceptual figure representing the analysis of the inner workings of AI (CNNs) to guide researchers' search for neuron types in biological brains; Center: Location opponent CNN neuronal units. One example of an emergent "neuronal" unit type in a CNN manifesting covert attention behaviors despite lacking a built-in attention mechanism. The type of neuron has not been highlighted previously in brains as related to covert attention. Right: Re-analyses of mice superior colliculus neuronal data (Wang, Herman, Krauzlis, 2022) showing location opponent and also location summation neurons.
