🚨 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.

Connectome datasets alone are generally not sufficient to predict neural activity. However, pairing connectivity information with neural recordings can produce accurate predictions of activity in unrecorded neurons

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.
