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 www.nature.com/articles/nrn...

With my great advisors and colleagues, @achterbrain.bsky.social @zhe @danakarca.bsky.social @neural-reckoning.org, we show that if heterogeneous axonal delays (imprecise) can capture the essential temporal structure of a task, spiking networks do not need precise synaptic weights to perform well.

#NeuroAI finds itself facing an interesting question these days: 1) which of these now-many schemes for bio-plausible credit assignment actually operate in the brain? -and if more than one- 2) how the hell do they operate when they, inevitably, interact?

#neuroskyence people (maybe vision people in particular): how do you think information is "read out" from the visual system? Do downstream areas like PFC get to query anything from V1 to IT? Or just later areas? How plastic are these readouts? Etc. IMO this is always under constrained in modeling.
