Jim was an incredibly gifted teacher. Still remember his fundamentals in Neuroscience. Also, great, dry sense of humor.

Latest from the lab. Beautiful work from Joanna Lau and a fantastic collaboration with James Fitzgerald. www.cell.com/current-biol...

Can't wait to read this preprint from Misha Ahrens and team. Calcium imaging in larval zebrafish, in every cell in the body! Amazing. www.biorxiv.org/content/10.1...

If you’re interested in ants, olfaction, gene regulation, or all of the above, here’s a new preprint from the lab for you. It describes an unorthodox mechanism of transcriptional interference by which ant olfactory sensory neurons produce a single functional receptor. www.biorxiv.org/content/10.1...

Neuronal diversity is written in transcriptional codes 🧬. But what is the logic of these codes that define cell types and wiring patterns? To find out we built a #scRNAseq developmental atlas of the Drosophila nerve cord and linked it to the #connectome 🪰🧠 #preprint thread ⬇️1/8

1. "'Trusting the experts is not a feature of either a science or democracy," Kennedy said." It's literally a vital feature of both science and of representative democracy. I've written a fair bit about trust in expertise as a vital mechanism in the collective epistemology of science.

ok, this just posted. It's a sincere question, and I'm hoping that responses to it/discussions of it will clarify questions that many of us have about claims being made about putatively disruptive effects of AI on how we think about the brain. doi.org/10.21428/8e6...

One of the weirder scholarly practices regarding generative AI that seems to have been normalized is citing chatbots. I say normalized because many univs & scholarly associations recommend it as an element of proper scholarship. But it doesn't make sense when you consider what a citation means. 1/
