Both leaders and followers integrate partner position into their decision-making, exerting asymmetric yet reciprocal influence. Forward multi-agent RL (MARL) shows simulated agents can learn the task and also develop stable leaderāfollower dynamics, suggesting social roles can self-organize (2/5)
Thanks so much for the generous support from @sinaibrain.bsky.social and the Glickenhaus Family!
Thank you to the McKnight Foundation for this incredible honor. I'm deeply grateful to my lab, mentors and colleagues, and especially thankful for the unwavering support of Mount Sinai community. This reflects a true team effort, and I'm excited for the work ahead!š§ š
Fascinating! The use of social gaze seems quite complicated in these cooperating marmosets
To uncover latent strategies, we built a multi-agent inverse RL (MAIRL) model with joint value decomposition. MAIRL infers individual goal and interaction maps that mirror asymmetric neural codes and are decodable from mPFC population activity, linking behavior, circuit, and computation (4/5)
The medial prefrontal cortex (mPFC) represents both trial-by-trial leadership dynamics and enduring social roles. It also encodes a role-based, egocentric āsocial value mapā of partner's position that adapts to task demand. Disrupting mPFC impairs cooperation and shifts selfāpartner weighting (3/5)
Super excited to share the first cooperative foraging paradigm in freely interacting mouse pairs! Stable leader and follower roles emerge spontaneously and predict learning. Well-trained mice show stereotyped, role-specific ābehavioral motifsā absent in naive animals (1/5)

This was a truly collaborative effort and will open new avenues to probe social cognition and collective behavior. Huge thanks to the amazing team who made this cooperationš possible! @esschaffer.bsky.social @nuttidanuttida.bsky.social @talmo.bsky.social @nan-mssm.bsky.social (5/5)

Very excited to announce our latest paper uncovering circuit, cellular and molecular mechanisms underlying the formation and maintenance of social hierarchy, another terrific collaboration with @neurovenki.bsky.social, Vic Kapoor and Adam Nelson (not on bsky) www.sciencedirect.com/science/arti...
