Hard to overstate how pleased I am that the FlyWire consortium converted our FAFB ("Full Adult Fly Brain") EM volume into a connectome, and that the resulting science has been (and will be) so impactful. Thanks to everyone involved. #neuroscience www.nature.com/immersive/d4...

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

Davi Bock @dddavi.bsky.social · 5h

🤚❓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 :)

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. :)

To celebrate the first anniversary of the release of FlyWire, we asked nine neuroscientists to share how they are using connectome data in their research and what they hope is in store for the future of fly connectomics.

Ed Kravitz passed away yesterday.
He was a remarkable scientist and mentor- brilliant, curious, creative, and kind. I am grateful to have learned from him. His legacy will endure through his science and through the many people he inspired.

We will miss you, Ed.

Per NSF staff, the solicitation was cleared in the system, and should have posted automatically on the next business day. So it is being manually held—there's not some kind of logistical issue. Unclear what the rationale for this is.

I don't know that it works perfectly, but I have to say that the Asta search tool from @ai2.bsky.social is exactly what I want from an AI-powered research search tool for scientists: Describe a style of experiment or work and see if there are papers that have done that.

Synaptic connectomes also look like this. Protein & gene interaction networks as well. Fractal recurrence across scales, from brain regions all the way down to molecules -- essential to biological information processing, yet so poorly understood.

Do you know what happens when you touch a carnivorous sundew plant?
If the touch is strong and large enough, a cytosolic calcium wave will spread from the site of touch throughout the whole plant, but if you only touch one tentacle (see post below), the calcium wave will be local and less intense.

Whoa - neuronal ciliary proteome! Tons to dig into here - different from kidney cilia proteome (perhaps unsurprising) and enriched for many postsynaptic proteins, strengthening previous suggestions of cilia as postsynaptic signaling structures.
