Just published – “The dynamics and geometry of choice in the premotor #cortex” by Genkin et  al. shows how the #brain encodes #decisions. Using single-trial #NeuralRecordings, they model #decisionmaking as 1D trajectories on a high-dimensional #manifold.

Key findings:
Diverse tuning curves reflect one latent decision variable
Dynamics follow an attractor
Geometry links sensory & cognitive coding

Building the SDS (SubDivisionSurface) from optionally hollow cylindrical sections is working out really well

Could you imagine playing a "not-really-tower-defence" on the inner/outer surface of this?

Need-to-add: pretty much everything, sharp edges, branching...

Please-excuse: lighting, grid positioned by hand in only approximately the right place...

Hmm, making an #RSS for #Polymarket might be interesting... And/or #Manifold. I could add it to my daily/weekly briefing folder.

I'm surprised nothing like this exists already.

The question is how to present it; maybe that's why.

One zone in our underfloor heating system stopped working, but now I understand the whole system inside and out. I’ve learned terms like #Manifold and #Actuator, plus I know how to bleed #UFH and replace an actuator pin. Well done, me!”
