stefanofusi.bsky.social @stefanofusi.bsky.social · 06/08/2026Specialized readouts are also possible when most neurons are not specialized, if you have the right representational geometry. Another great work with D. Salzman's lab: led by Pia O'Neill and @lorenzoposani.com, who did a wonderful job 0194

Now @stefanofusi.bsky.social, @lorenzoposani.com & Liam Paninski present new evidence in @nature.com shedding light on how the brain performs complex tasks. tinyurl.com/yj3ew8en 04213

Whether modularity emerges or not strongly depends on the geometry of the inputs and other factors. Extensively revised article with many new results. With @wjj.bsky.social 0174
Reposted by @stefanofusi.bsky.socialNicholas Menghi @nichome.bsky.social · 02/12/2025Our new paper, now published in @natcomms.nature.com , asks a simple question: when two tasks share a common structure, does the brain learn them more efficiently? Surprisingly, this was not the case.
