A global dopaminergic learning rate enables adaptive foraging across many options

This study develops a reinforcement learning model to understand how mice adaptively forage across multiple options, finding that dopamine in the nucleus accumbens core reflects a global learning rate.

Nucleus accumbens D1-receptors regulate and focus transitions to reward-seeking action

This study investigates the role of D1 receptors in the nucleus accumbens core in regulating reward-seeking behavior during Go/No-Go tasks in rats.

5-HT2C receptor perturbation has bidirectional influence over instrumental vigour and restraint

This study examines how 5-HT2C receptor perturbation affects instrumental vigour and restraint in rats, finding that systemic activation boosts performance and reduces restraint, while dopamine enhances restraint and action initiation.
