🚨🚨🚨NEW PREPRINT🚨🚨🚨

A big mystery in brain research is what are the neural mechanisms that drive individual differences in higher order cognitive processes. Here we present a new theoretical and experimental framework, in collaboration with Vincent Tang, Mikio Aoi, Jonathan Pillow, Valerio Mante, @SussilloDavid and Carlos Brody.

This is really exciting. Congratulations!

Here we've been talking a lot about complex dynamical systems, and I have so many questions.

First one: Over on the bird site, @SussilloDavid wrote, "Hell, I’ll go bigger. This work provides strong indirect evidence for the computation thru dynamics framework."

Can you please unpack that just a bit more @SussilloDavid ?

@NicoleCRust @marinopagan @SussilloDavid @PessoaBrain @DrYohanJohn @manlius @neuralengine @cogneurophys @complexsystems yeah. I am quite unclear how else we could compute than through dynamics. So would be very curious about the answer.
@kordinglab @NicoleCRust @marinopagan @SussilloDavid @PessoaBrain @DrYohanJohn @manlius @cogneurophys @complexsystems
Yes I agree with you Konrad. I guess one could view computations that used only steady state processes to be not computing "with dynamics". (But they would still have dynamics).

@neuralengine @kordinglab @NicoleCRust @marinopagan @SussilloDavid @PessoaBrain @DrYohanJohn @manlius @cogneurophys @complexsystems We found evidence that individuality in odor-choice assays can arise in the sensory periphery https://www.biorxiv.org/content/10.1101/2021.12.24.474127

We think of it as differences in odor-coding rather than dynamics, but I suppose some brief integration is needed to realize small individual differences in firing rates.
