Topic: generalized representations

The hippocampus plays a key role in cognitive map formation. As an abstract model of the world, it has to balance the demands of accurate, yet general, predictions. Despite a long-lasting interest in hippocampal computations, the specific contributions of distinct hippocampal subregions remain debated. Evidence from rodents and humans suggests that subregion CA3 represents event-specific information, while subregion CA1 encodes more generalized information.The free-energy principle entails that neural networks with more generalized representations operate closer to criticality, where external
