“A Computational Perspective on the No-Strong-Loops Principle in Brain Networks”
www.biorxiv.org/content/10.1...
Over the past 3 years, we’ve been investigating why cortical networks avoid strong reciprocal loops — and what this means for computation.

How should #multisensory signals be combined when they are structured in time?
To explore this, we:
* Introduce a new multisensory task
* Compare several models
TLDR:
* Prior models perform suboptimally
* Our new model performs ≈ an RNN, while using less than 1/10th the number of parameters.

Now published at PLOS Comp Biol! 🎉 With @swathianil.bsky.social and @marcusghosh.bsky.social.

TLDR, when multisensory signals vary over time, neural architecture becomes important. Biggest not always best.
