This study trains a bimodular spiking actor-critic network on an economic choice task to explore how value and action representations emerge in distributed neural circuits.

The paper shows that perceptual biases in working memory arise from neural encoding in both prefrontal cortex and secondary somatosensory cortex, suggesting a distributed cortical mechanism.

This study identifies neural correlates of perceptual bias in the prefrontal cortex of monkeys using vibrotactile frequency discrimination task data.

This study trains spiking recurrent neural networks to discriminate time intervals and finds that they exhibit contraction biases similar to animal behavior, encoded through geometric features of neural trajectories.

This study investigates how GABAB receptor modulation affects slow oscillatory rhythms in cortical networks through combined experimental and computational approaches.

This study shows dopamine firing encodes reward prediction errors and motivation during a working memory task in monkeys, with distinct roles for phasic and tonic activity.

The paper examines how internal bias influences dopamine neuron activity during decision-making tasks in monkeys, showing bias affects phasic activity and reward prediction errors but not delay period activity.
