Hebbian plasticity has long dominated neurobiological models of memory formation. Yet, rules operating on one-shot episodic timescales rarely depend both pre- and postsynaptic spiking, challenging theory in this crucial regime. Here, we present an model governed by a simpler rule depending only presynaptic activity. We show that rule, capitalizing high-dimensional neural activity with restricted transitions, naturally stores episodes as paths through complex state spaces like those underlying world model. The resulting traces, which term path vectors, are highly expressive decodable odor-tracking algorithm. vectors robust alternatives to support sequential associative recall, along policy learning, shed light specific hippocampal rules. Thus, non-Hebbian is sufficient for flexible learning well-suited encode policies

ABSTRACT Do animals have episodic memory—the kind of memory which gives us rich details about particular past events—or is this uniquely human? This might look like an empirical question, but attracting increasing philosophical attention. We review relevant behavioural evidence, as well drawing attention to neuroscientific and computational evidence has been less discussed in philosophy. Next, we distinguish evaluate reasons for scepticism animals. In the process, articulate three pressing issues underlying these sceptical arguments, should be focus future work. The Problem Interspecific Variation asks differences between humans animal mean that a variant memory, it different altogether. Functional how conceptualise functions other capacities across species evolutionary time. Finally, Alternatives what, besides explain evidence—and competing explanations.

The cognitive ability to go beyond the present consider alternative possibilities, including potential futures and counterfactual pasts, can support adaptive decision making. Complex changing real-world environments, however, have many possible alternatives. Whether how brain select among them represent alternatives that meet current needs remains unknown. We therefore examined neural representations of spatial locations in rat hippocampus during navigation a complex patch foraging environment with reward probabilities. found multiple along paths ahead behind animal, distant patches. Critically, these were modulated distinct patterns across successive trials: represented proportionate their evolving relative value predicted subsequent decisions, whereas prevalent updating. These results demonstrate modulates generation possibilities for behavior.
