The easiest way to learn something about a person’s character is based on whether they’re willing to get a shoeshine at the airport. If I see you doing that then I know everything about you that I’d ever need to know.

If you are at #SfN25 and curious about infant 7T research, reach out to chat!
This work, a collaborative effort between MIDB and the University of Minnesota's Center for Magnetic Resonance Research, provides a first glance on what we can achieve with 7T MRI in infants and highlights its role as a promising new avenue for developmental cognitive neuroscience 🧠
🚨 New preprint on the first infant 7T MRI project in North America! www.biorxiv.org/content/10.1...
We showcase that by leveraging 7T for infants, we can improve data quality and thereby facilitate precision functional mapping in early development.

New evidence shows that neurons of the same specific type tend to avoid each other in space, supporting the mosaic hypothesis in the cortex.

Very excited to share that our work (together with co-first author Shanka Subhra Mondal and @neuroai.bsky.social ) on a brain-inspired architecture for planning with LLMs is now out in Nature Communications! www.nature.com/articles/s41... (thread below)
A brain-inspired agentic architecture to improve planning with LLMs - Nature Communications
Multi-step planning is a challenge for LLMs. Here, the authors introduce a brain-inspired Modular Agentic Planner that decomposes planning into specialized LLM modules, improving performance across tasks and highlighting the value of cognitive neuroscience for LLM design.
