Oh man. Science Neural Circuits would be my new favorite journal.

Ahhh this is great. I remember @repromancer.bsky.social taking about this when he was working on his EG paper: www.biorxiv.org/content/10.1...
Did not realize it came from Amari

Ahh good to know re: reproducibility.
Jascha actually came and presented the delay learning stuff here a few weeks ago, super cool! Made me think it’s time to get into training some spiking networks 😉

I’ve also always wondered how all these D’s relate - coding, communication, fractal, movement-related 😵💫

Off-manifold coding in visual cortex revealed by sleep
Low-dimensional neural manifolds are controversial in part because it is unclear how to reconcile them with high-dimensional representations observed in areas such as primary visual cortex (V1). We ad...

Could you recommend an “Amari to the rescue” paper to start with? Have been meaning to dig into his work.

During my PhD, I remember someone saying something to the effect of “really easy to wake an animal up with neural stimulation, really hard to put them to sleep”.
That was until Yang Dan’s lab took up the challenge 😂

Might be wrong, but I think this has only been found in cortex?

Volitional control of single cortical neurons in a brain-machine interface
Volitional control of cortical activity is relevant for optimizing control signals for neuroprosthetic devices. We explored the control of firing rates of single cortical cells in two M. Nemestrina monkeys by providing visual feedback of neural ...

At least we get to say it like “d-pip”, which has a nice ring to it.

Most neuroscientists would agree that the brain is far more sophisticated than ANNs - so why would we force tools and interpretations that are too trivial to explain ANNs today, much less the brain? We wouldn't.
