If an action results in error, each neuron requires an individualized teaching signal that guides change in its output. This is the credit assignment problem of learning. Are there neurons in the brain that can compute such a sophisticated teaching signal? Yes. www.biorxiv.org/content/10.6...

What's the lowest effort way of having multiple people contribute to a list of papers? Assume no common existing apps. I was thinking just dump it into a Google Doc.

Happy Monday! Come learn how jellyfish swim. In a review led by fluid dynamics maestro Alex Hoover, we outline how neuromechanical modeling will help us understand how modulation of neural activity allows jellyfish to jet and pirouette through fluids www.sciencedirect.com/science/arti...

We're hiring! Postdoc position to study the neural control of reaching using high-density multi-area electrophysiology. 5 years of funding, great collaborative environment. Please share with anyone who may be interested. For details, see: docs.google.com/document/d/1...

Conrgatulations! Exciting times ahead.

Yes, but these are roughly split over the two competitions. Looks like more grants funded largely because, for whatever reason average grant size is smaller ($935K this round vs. $980K last round). Very curious to see if app pressure continues to grow.

I wonder where they got more money than last competition. I guess two options are that this 439 isn't full grant (includes bridges?) or that average funded grant size went down for some reason. ATB cut steady as 23.5%.

Official job posting coming when I get back from the cottage but if you're interested in a post-doc doing multi-area high-density electrophysiology in the cortico-thalamic circuit during reaching, feel free to reach out!

Very happy to receive a CIHR Project Grant to continue our work on how sensory signals are organized in the thalamo-cortical motor circuit.

LOL England

LOL France -- this game has less energy than the most random group stage matchup.

important paper to dig into!

England choke.

Well, as a sympathetic outsider, I disagree wholeheartedly with your assessment.

Thanks Adrian, that's clarifying.

Figuring out the state variable in the feedback controller for a given task is an important/interesting question. I don't see the clear line between internal model predictions and ecological information 🤷‍♂️.

I agree with Abby's interpretation that you don't need to solve some explicit set of equations. Is that all we are discussing here?

No one doubts the role of feedback in movement control. I am sympathetic to Gibson but most of the field seems to be arguing against a ghost -- purity tests and semantics. @earlkmiller.bsky.social's point is mechanistic and worthy of serious study, as is happening no matter how people feel about it.

Because obviously there is a mix of prediction and feedback control in the control of motor actions as has been documented by thousands of papers.
