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 uses dynamic Bayesian modeling to uncover causal interactions in primate prefrontal-amygdala networks during social gaze, revealing directional influences between brain regions.

The paper identifies a compositional neural code for social gaze in macaques, showing how primitives like content and state are abstractly represented in prefrontal-amygdala circuits.

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 shows that microstimulations of the orbitofrontal cortex during gaze interactions enhance dynamic social attention in monkeys.

The paper introduces a statistical framework to cluster neural activity into functional ensembles, demonstrating its application to social behavior data in rodents and primates.

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.

This study tracks 3D gaze and facial movements in marmosets to show how sex and familiarity influence social gaze patterns during interactions.

The paper examines neural responses in macaque brain regions during social gaze interactions, identifying single-cell representations of social gaze functionalities.

This study shows that increasing central serotonin with 5-HTP impairs the ability of rhesus macaques to inhibit social gaze orienting.

The paper examines neuronal synchronization between the medial prefrontal cortex and amygdala during social decision-making, finding enhanced synchronization for positive other-regarding preferences and suppressed synchronization for negative ones.
