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

- Reposted by Johannes LarschCan'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...
- Reposted by Johannes LarschIf 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...
- Reposted by Johannes LarschNeuronal 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

- Reposted by Johannes Larsch1. "'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.

We discovered that evolution, by acting in the midbrain, shifted the threshold to escape in Peromyscus mice, to fine-tune defensive strategies in different environments www.nature.com/articles/s41... This was a truly collaborative effort! 🧵⬇️
