- A thought-provoking perspective from the visionary @giacomoi.bsky.social, calling for neuromorphic computing to return to its root: fundamental neuroscience; an inspiring vision for the future of NeuroAI 🤩
- 🚨 New preprint! “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.
- The no-strong-loops principle: Across species (macaque, marmoset, mouse), strong reciprocal (symmetric) connections are rare. This asymmetry is well known anatomically. But what are its computational consequences?
- In earlier work (www.biorxiv.org/content/10.1...), we developed Network Reciprocity Control (NRC): algorithms that adjust reciprocity (link + strength) while preserving network structure. In this study, we apply NRC to systematically test how reciprocity shapes computation in recurrent networks.

- Wonderful work by Shrey and Kayson in developing an XAI method for exploring the contribution of any computational unit (e.g., nodes, experts, communities, filters) within neural networks. It enables analysis of both their influence on each other and their overall impact on task performance.

- Reposted by Fatemeh_HadaeghiHow 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.
- Fusing multisensory signals across channels and time. Now published at PLOS Comp Biol! 🎉 With @swathianil.bsky.social and @marcusghosh.bsky.social. journals.plos.org/ploscompbiol... TLDR, when multisensory signals vary over time, neural architecture becomes important. Biggest not always best.
