The paper examines vocal signaling in marmoset dyads during cooperation, finding that social hierarchy and task role determine which vocal signals are used and when.

The paper identifies a neural mechanism in the dmPFC of marmosets that uses social gaze to accumulate evidence for cooperative decisions.

This study shows marmosets use flexible, cognitively driven cooperation strategies in dyads, adapting based on partner identity and social relationships.

The paper introduces MarmoAAP, a novel apparatus for studying cooperative behaviors in common marmosets, enabling high-throughput behavioral data collection and integration with video/audio for detailed analysis.

The paper shows that orbitofrontal cortex (OFC) neurons contribute to value comparison in economic choices by disrupting the decision process without affecting offer values through electrical stimulation.

This study investigates choice biases in economic decisions under sequential offers in rhesus monkeys, identifying distinct neural stages responsible for accuracy, order bias, and preference bias.

The paper shows that the same neural circuit in the orbitofrontal cortex supports economic choices under simultaneous or sequential offers.

This study shows that electrical stimulation of orbitofrontal cortex in rhesus monkeys biases economic choices by altering encoded values.
