The paper shows that value representations in ACC and OFC develop rapidly and use distinct coding strategies, with ACC encoding generalized value and OFC showing context-dependent coding.

This study identifies neural signatures of model-based and model-free reinforcement learning in prefrontal cortex and striatum using single-neuron recordings in rhesus macaques.

The paper shows that the anterior cingulate cortex encodes the value of peripheral cues before fixation to guide subsequent fixations and choices during economic decision-making.

This study combines model-free and model-sensitive reinforcement learning in rhesus monkeys, showing both strategies influence decision-making and response vigor.

The paper demonstrates a triple dissociation of attention and decision computations across three prefrontal cortex subregions during value-guided choice.
