The paper shows that OFC population activity in mice exhibits task-specific attractor-like dynamics during belief-state inference, mirroring Value-RNN dynamics.

This study investigates the role of dopamine in conditioned responding, finding that it directly modulates responses beyond its role in learning.

The paper demonstrates that TD learning computations are hardwired into a dopamine circuit by showing optogenetic stimulation of NAc D1 neurons drives dopamine neuron spiking according to TD error.

Repix enables reliable, reusable, and versatile chronic Neuropixels recordings in unrestrained animals over months, with minimal user training and high stability.

This study investigates how dopamine signals in the ventral striatum relate to contingency during associative learning in mice, finding that TD learning models with ITI state representations explain the results better than contingency-based models.

This paper shows monkeys adjust their reward-effort decisions based on subjective effort costs influenced by prior experience, using a subtractive model of effort disutility.
