One example of how multiplexing might be implemented in the brain was shown in the great work by Thomas Akam with Dmitri Kullmann, a decade ago.
The papers are cited well but the general multiplexing idea never really took the field by storm as much as it deserved

It feels like the converastion about manifold dimensionality is back, so I thought I'd share a paper that explains nicely why measuring the "embedding dimensionality" of a manifold (e.g., counting PCs) can be very different from its actual "intrinsic dimensionality (DoFs)

I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far). try it: planyourscience.com

The Ponizsa illusion - Kanizsa triangle produces Ponzo illusion, but oddly it inverts apparent depth: the longer line looks closer! Also has an inversion effect like we studied in Altan et al 2025 Proc Roy Soc (doi.org/10.1098/rspb...) but it's also in reverse! 🤔

The US is an evil nation
"Like a bunch of gangsters": 100+ nations were set to approve a historic plan to slash pollution from cargo ships. Then the US stepped in. Diplomats were stunned by “nasty” and “very personal” threats, including blacklisting, financial penalties, tariffs, sanctions, and the revocation of US visas.
