Delighted to share our discoveries about one of the brain's neurotransmitter systems:

Together with colleagues at the @alleninstitute.org, we have learned a lot about a tiny cluster of neurons in the brainstem locus coeruleus (LC) that releases norepinephrine (NE). 1

๐Ÿ—ฃ๏ธ Language is widely distributed throughout the brain ๐Ÿง 

In a recent correspondence in @natrevneurosci.bsky.social, we suggest that there is no 'language network' in the brain. What appears as such is an inevitable illusion created in part by the methods we use.

Writing philosophy is like 'thought archaeology'--each rewrite and revision dregs up more and more of the underlying thought process that produced the text. Good but tiring!

Preprint out arguing that we should build the techology to translate (compile) molecularly annotated connectomes into dynamics. I think this is incredibly important. arxiv.org/abs/2603.25713

On the invitation for a commentary on Mazviita Chirimuuta's The Brain Abstracted, I had the pleasure of writing on equating the brain with computation.

Our latest publication grapples with how the brain could implement gradient descent by sending learning targets top-down, gating plasticity with dendritic inhibition, and updating synaptic weights with biologically observed learning rules like BTSP.

If you're interested in emerging ideas in neural interfaces, I humbly suggest my lab's latest: www.nature.com/articles/s42...

Neural interfaces create dynamic interactions between the brain & devices. This means mean we need new engineering approaches beyond typical ML to "decode" a static brain

What are the systems in neuroscience that we really have something that we can call โ€œexplanationโ€ at all relevant levels, other than reflexive feed-forward like circuits.

Here are a few that I would argue are getting there. Obviously not complete explanations but genuinely satisfying.

Iโ€™m excited to share my newest work with @benhayden.bsky.social, and the work Iโ€™m most proud of to date, on characterizing semantic coding in single-neuron hippocampal activity in patients with autism during natural language comprehension!

The last year has been an extraordinary journey for us at @elife.bsky.social as we have been establishing a new model of publishing and taken on some of the commercial forces in publishing. We have tried to capture some of the takeaways in this editorial.
