How can we build better experiment-theory collaborations in neuroscience?

We're hosting a series of 6 in-person, interactive workshops to discuss this.

Come along!

Iโ€™m a bit late to reading this article by @marcusghosh.bsky.social in the @thetransmitter.bsky.social
I really enjoyed it.
Iโ€™m definitely pro toy mathematical models, I believe they can be informative and push research forward.

2025: A Review of the Year in Neuroscience Enlightening the brain

Just published my review of neuroscience in 2025, on The Spike.

The 10th of these, would you believe?

This year we have foundation models, breakthroughs in using light to understand the brain, a gene therapy, and more

Enjoy!

Remembering Adam Kampff, neuroscience educator and researcher Kampffโ€™s do-it-yourself approach inspired a generation of neuroscientists.

Adam Kampff prioritized spreading knowledge over publishing flashy papers in prestigious journals, but colleagues say his mark on neuroscience was undeniable. The researcher and educator passed away on 9 December.

Thatโ€™s exactly the right question!

What is the smallest / simplest model for your phenomenon of interest.

Some recent work, cited in the article, shows that very small models can be surprisingly powerful.

And often we may be far above the lower bound, which then hinders interpretability

2. Brains are massively complex, but if our goal is to understand them, then building scale models may not be the best approach.

In physics, many breakthroughs have come from abstracting away complexity, as this article highlights!

Thanks for reading the article!

1. The multi-billion parameter model discussed in the article was developed by Meta but then fine-tuned by neuroscientists (for research).

This could become more common, or neuroscientists could start to train their own "foundation" models from scratch.

Adam was a truly inspiring scientist.

He made neuroscience fun and exciting, and made everything seem possible.

The Behaviour and Neural Systems course was formative for many of us.

Actually, according to an eLife information session, eLife desk reject ~90% of submissions.

So the ones which do get reviewed tend to be high-quality!

Even if, like the paper @neural-reckoning.org is referring to, the reviewers don't agree with everything.

You may be interested in our recent work too!

We define 128 RNN architectures then compare their behaviour and dynamics (using gradient-based metrics).

๐Ÿ“Excited to share that our paper was selected as a Spotlight at #NeurIPS2025!

arxiv.org/pdf/2410.03972

It started from a question I kept running into:

When do RNNs trained on the same task converge/diverge in their solutions?

@neural-reckoning.org and I defined a taxonomy of neural network architectures, which we exhaustively explored!

We think these models (pRNNs) are exciting for thinking about structure-function relations in artificial and biological neural networks.
