@dddavi.bsky.socialare you helping me or hurting me with this information!? 😉

@dddavi.bsky.social@dddavi.bsky.socialThe Transmitter @thetransmitter.bsky.social just published a piece on this: www.thetransmitter.org/connectome/b...
@dddavi.bsky.socialFetching? This seems to be drilling, in case of future necessity! Serious business.
@tuthill.bsky.socialReposted by @dddavi.bsky.socialtwo new preprints from Wangchu Xiang (@darbly.bsky.social, Ginty labs) about connectomic reconstruction from electron microscopy of somatosensory afferents and projection neurons in the dorsal horn of the mouse spinal cord

@neurosock.bsky.socialReposted by @dddavi.bsky.socialMix. selectivity is everywhere in cortex: from vis. to PFC
This paper relates to Cover's theorem but the typical explainer kind of sucks
I'll try to explain how the theory relates to the paper, and the importance of "weird" neurons
A🧵with my toy model and notes:

@dddavi.bsky.socialTRUTH
@dddavi.bsky.socialremember that egg in a little cup on a table in Berlin… there is clearly some overlap in how our visual systems operate
@dddavi.bsky.socialOK this one too. I’ll just return to not replying to these Porsche posts of yours :)
@dddavi.bsky.socialthat one really is
@dddavi.bsky.socialthe link seems to be to some kind of spam site
@dddavi.bsky.socialhere's a link to @zhihaozheng.bsky.social et al.'s paper if anyone is curious: www.cell.com/current-biol...
@ivychanchiwai.bsky.socialReposted by @dddavi.bsky.socialOur paper on odour categorization in the Drosophila mushroom body is now out in Cell Reports! 🎉
We found that αβ and α′β′ Kenyon cells—but not γ KCs—distinguish food-related from non-food odours at the population level.
Very happy to see this work published! 🪰🧠
@dddavi.bsky.socialVery nice to see this extension + (most importantly) functional assay of our initial observation of non-random overconvergence of food-responsive PNs onto downstream aB and a'B' KCs (@zhihaozheng.bsky.social et al. Curr Biol 2022). Connectomics leading to testable hypotheses: as it should be!😀
@dddavi.bsky.socialNot assuming anything, I just want to know what the setting was. :)
@dddavi.bsky.socialClaude has a privacy setting for whether or not your sessions can be used to train their models. I'd like to know what the setting was in this case.

Ben Hartl explains:
In 1917, D'Arcy Thompson drew Cartesian grids around different anatomical shapes & showed that deforming the grid could change one species' shape into that of another. We find that "reusable regulatory handles control phenotypic variation" in NCAs
@couchmicroscopy.bsky.socialReposted by @dddavi.bsky.socialProtists deserve the spotlight and so do scientists! This was such an honor but mostly, this project reminded me why I have the best job and friends/colleagues in the world! 🔬
