In the spirit 👻 of Freaky Friday 🎃, here is a beautiful yet eery video of zebrafish retina development showing horizontal cells (🔵) finding their way out of the crowded amacrine (🟠) layer to settle beneath the photoreceptors. Happy #Halloween!

Our paper is out! Take a look if you’re curious to see how we use expansion microscopy on diatoms ☺️ Very excited to keep using this!!

After 13 years in the US, I’ve made the difficult decision to leave. Having packed up everything and rethought about priorities, rather painstakingly, while I’m sad to leave the life I’ve made here, I’m also relieved that I won’t have to plan my life around immigration policies anymore.

What a time to be alive

Thank you so much @wellcometrust.bsky.social for supporting us to push the the limits of #X-ray #nanoimaging and #connectomics, and to make technology more broadly available to the scientific community! 🙏

Nice visualization. Maximize for full effect.

Remembering GABA pioneer Edward Kravitz The biochemist, who died last month at age 92, was part of the first neurobiology department in the world and showed that gamma-aminobutyric acid is inhibitory.

Edward Kravitz, a Harvard biochemist who proved GABA's inhibitory power, passed away last month. He will "be remembered for his humanity, for his social conscience and his desire to help those less fortunate than he,” says Ronald Harris-Warrick.

New preprint from the lab: A reference brain for the clonal raider ant.
With this resource, which is based on 40 individual brains, you can register and compare all kinds of samples in a common space. It comes with lots of detailed protocols and a user-friendly GUI.

Expanded mouse olfactory bulb imaged with fluorescence at 20-50 nm resolution!

Ingenious concept - light sheet on serial sections by photo-etching the expanded hydrogel, layer by layer.

Photo-sectioning is quite slow, and the volumetric images are insanely large and complex, but the data look wonderful.

Interesting answer from Mark to a question I had about his piece on recurrence and active filtering in sensory cortex (at www.annualreviews.org/content/jour...)

thanks for the answer, interesting overall, + interesting to think about "comparative recurrence" as a target of study..

🤚❓Massive recurrence is not unique to cortex but rather permeates the CNS of all animals studied so far. How do you think about this? Maybe you would argue that active filtering in cortex is a special use of recurrence? Or maybe the converse, that active filtering happens everywhere?

& hi Mark :)

Our group at the Allen Institute is recruiting a technician and postdoc to work on light microscopy-based connectomics. Please DM me or share with anyone you think may be interested in this NIH BRAIN CONNECTS funded project.

😂

Half!? I'm impressed you give it that much! :)

I love this piece!

It shows the many ways a connectome can be put to use, AND the many complementary modalities that are needed, beyond the connectome, to answer real questions.

And it makes me feel good about having helped to generate the thing. :)

Rendering this video was a nice test for #Blender3d, as the full set of bodies visible by the end involved almost 1.1 billion polygons. It all worked out well on our H200 cluster.

Exciting news for #drosophila #connectomics and #neuroscience enthusiasts: the Drosophila male central nervous system connectome is now live for exploration. Find out more at the landing page hosted by our Janelia FlyEM collaborators www.janelia.org/project-team....

Nice. And I bet with a loupe you could see synapses in the prints. :) What paper is this from?

Keeping in touch with the road not taken Nature Structural & Molecular Biology - Keeping in touch with the road not taken

I am so happy this perspective was published today, on Thanksgiving day!! 🥂🦃

I reflect on how keeping in touch with a field I left behind long ago continues to bring me joy and fulfillment.
