@SMikulovic @NatureNeuro @tararaam_ Thanks Sanja!

@TheHongLab @NatureNeuro Another fantastic piece of work! Huge congratulations, @tararaam_ and @TheHongLab!

We often think of survival as an individual act. But when facing hardship together, social groups may function more like a unified system than a collection of separate individuals Excited to share our latest work @NatureNeuro on collective social dynamics rdcu.be/e8LrV

Interestingly, silencing the activity of this region selectively reduced active decisions in targeted mice but elicited compensatory increases in non-manipulated partners, preserving overall group-level huddle time.

At the neural level, we found that the prefrontal cortex tracks not just an individual's own choices, but also those made by its social partners, suggesting the brain continuously models others to enable coordinated group behavior.

Symposium Proposal Deadline Extended! 2026 Annual Meeting of the Society for Social Neuroscience (S4SN 2026) will take place in Montréal, Canada, August 23–26, 2026 The deadline for symposium proposals has been extended to Tuesday, March 31 Learn more: s4sn.org/s4sn2026

We find that specific neurons in the medial preoptic area that regulate parenting are also critical for comforting behavior toward adults. This suggests that neural systems evolved for offspring care may have provided a scaffold for broader prosocial support between adults.

While prosocial helping behavior is hypothesized to have an evolutionary root in caring for vulnerable newborn offspring, whether the neural substrates underlying parenting may contribute to adult-directed prosocial helping behaviors remains largely unclear.

@moccalin @pgolshani @ScienceMagazine @JanineJiang22 @JonathanCKao Thanks Dayu!

@TheHongLab @pgolshani @ScienceMagazine @JanineJiang22 @JonathanCKao Congrats again! Hope all is well.

We are excited to share our latest work in @ScienceMagazine studying cooperative behavior in both biological and artificial intelligence systems — fantastic work by @JanineJiang22, Linfan Gu, and wonderful collaboration with @JonathanCKao! science.org/doi/10.1126/sc…

We extended our findings to artificial intelligence systems by training artificial agents in a similar cooperation task using multi-agent reinforcement learning (MARL). The agents developed behavioral strategies and neural representations reminiscent of those observed in the biological brain, revealing parallels between cooperative behavior in biological and artificial systems.

We identified key social behavioral strategies and decision-making processes in mice that facilitate successful cooperation. We found that these processes are represented at both single-cell and population levels in the anterior cingulate cortex (ACC) and demonstrated a causal role for ACC activity in cooperation.

@pgolshani Congrats Peyman and Jiannis!

Very proud of this new paper led by Jiannis Taxidis in Nature Neuro where we use voltage imaging, optogenetics and ephys to record and manipulate PV and SOM interneuron activity patterns during working memory performance! nature.com/articles/s4159…
