Predictive learning induces Bayesian cognitive maps in the hippocampus

This study shows that predictive learning in recurrent neural networks generates Bayesian cognitive maps similar to hippocampal place cell activity, outperforming autoencoders.

Uncertainty underlies geometric effects on navigation and grid-cell tuning

The paper shows that spatial uncertainty, influenced by environmental geometry, explains navigational behavior and grid-cell properties through a Bayesian model.

Multiple decisions about one object involve parallel sensory acquisition but time-multiplexed evidence incorporation

The paper investigates how the brain processes two decisions about one object, finding parallel sensory acquisition but time-multiplexed evidence incorporation.

Estimation of time-varying decision thresholds from the choice and reaction times with no assumption on the shape

The paper introduces a fast heuristic algorithm to estimate time-varying decision thresholds from choice and reaction times without assuming their shape, outperforming conventional methods under time constraints.
