This study shows that rats' anterodorsal striatum and prefrontal cortex work together in a recurrent circuit for evidence accumulation, with bidirectional communication and robustness to perturbations.

The paper tests whether rats use an integration strategy or degenerate strategies in a perceptual decision-making task and finds they predominantly use integration.

The paper introduces a cell-type dynamical systems model to better capture neural dynamics by considering distinct cell classes, showing improved accuracy and biological interpretability in decoding behavior and simulating perturbations.

The paper identifies transitions in neural dynamics and modes during perceptual decision-making in rats, linking these transitions to decision commitment.

The paper evaluates a correction method for slow drifts in decision criterion, showing it fails for common updating strategies and proposes a model-based approach to better disambiguate drifts from systematic updates.

This paper demonstrates a method for long-term, multi-probe Neuropixels recordings in freely moving rats over multiple months, showing high yield and probe reusability.
