If you are interested in serial sectioning for electron microscopy, we have now uploaded a revised version of our paper Shahidi et al: "Volume Electron Microscopy: Tips & Tricks on Micromanipulator-Assisted Serial Sectioning for Array Tomography" […] [Original post on biologists.social]

Our 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! 🪰🧠 doi.org/10.1016/j.ce...

Very 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!😀

Claude 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.

That contextual signals are broadly available does not mean that signals everywhere are used, or causally involved in behavior, at every moment. They aren’t. A bit like a radio broadcast, information may be widely available while circuits selectively “tune in” when needed. So where still matter.

This profile of the artist on the Challenger expedition and his contributions to protistology was a very nice Saturday morning read. Though with some irksome bits...
"Remarkably, in 1878, the same figures appeared in both books and an article by Ernst Haeckel (1878a, 1878b) with one figure rotated, and all given binominal names, without any attribution in the figure legends or in the text (Fig. 11). Haeckel's appropriation of Wild's figures was far from the last."
