As a former selection committee member, I can say it's really quite a joy to learn about all of your interesting directions!

(4/4) In mecp2 mutants, an autism model, we show that predictive information is reduced overall, but especially for synergistic flows, an indication of difficulties in more complex social behaviors. We look forward to a continuing conversation about what it means to be (quantitatively) social!

(3/4) We ground our approach in the body trajectories of two adult zebrafish engaged in a dominance contest. We find that information flows align with concepts such as dominance and mirroring, and that asymmetries in self-unique and redundant information reflect the emergent dominance relationship.

(2/4) Even in this era of pose tracking of almost any organism, the analysis of social behavior is challenging, often using specific assays and human-derived labels. We instead suggest that redundant, unique, and synergistic predictive information flows provide a natural set of social variables.

We are happy for feedback and plan to add more!
