Brain networks have evolved to be highly efficient and robust while consuming minimal energy. They possess unique properties such as sparsity, complexity, and small-world nature. Studies suggest that a trade-off between minimal wiring cost and efficient communication shapes brain network development. However, it's not entirely clear what factors are influential and to what extent each factor contributes to this development. This research examines several potential underlying factors and finds that with connectivity guaranteed by fixed degree distribution, minimizing wiring cost has the largest impact on network structure among all factors, such as maximizing the clustering coefficient or coefficient of variation for wiring length distribution. Without degree constraints, the cost-efficiency balance reproduces optimally brain networks of five species, but minimizing wiring cost remains the primary determinant.

Wiring Cost Minimization: A Dominant Factor in the Evolution of Brain Networks across Five Species

This session has no scheduled virtual poster presentation time, but attendees will be able to comment and ask questions about your work/research asynchronously throughout the conference.<br>

**If you are a virtual poster presenter**, you can leave a message in your poster area chat space to advise times (and time zone) that you will be available either in the chat box, or by setting up your own online meeting room (Zoom, etc.).<br>
**If you are an attendee**, please check each poster's chat box and arrange time with presenter.<br>

The 45th Annual Meeting of the Cognitive Science Society will take place in Sydney, Australia as a modified hybrid conference. Presentations from the main-session room will be live-streamed every day for all events. This will include all invited talks and award sessions. Recordings of all CogSci 2023 sessions will be made available for on-demand viewing after the conference.<br>
The in-person component will be held at the International Convention Centre Sydney at Darling Harbour. The Conference will take place Wednesday July 26th – Saturday July 29th, 2023 (Wednesday, July 26th is the Workshops Day).
