Attempting to declutter a microscope, @thorlabs.bsky.social are once again legends for providing the schematics to all of their products! All I had to do was line up the schematic for their shutter controller with the one for their XT95 optical rail, add a few holes for screws, et voila!

When you join a lab to do some voltage imaging

The hardest part about writing a review article, is composing emails to your colleagues that don't immediately get flagged as spam

If you think you're having a bad day: I just emailed someone to congratulate them with publishing a cool paper on a niche topic they've been working on for years, only to realize moments later that the paper was actually by someone with the same first name but different last name.

Me, a cool neuroscientist, wondering what the two smelly nerds are fighting over

For those of you keeping score at home: that is now 3 times Helthjem as attempted to deliver the same package to me, forgetting to actually bring it along each time. Mail delivery in Norway and Sweden is truly comically bad.

Past me: "I am going to cable-manage this setup properly, not let it devolve into a tangled mess of cable-spaghetti!" Current me: *quiet sobbing*

"Nah, I won't need to bring my notebook, I just need to take this one measurement"

✨ New preprint ✨ What if we could watch AND control thousands of individual neurons in behaving mice—with stable access over months? 🧠⚡ Our work introduces transgenic all-optical tools that make this possible - and a resulting surprising discovery! 🔭💡 www.biorxiv.org/content/10.1... 1/13 🧵

Our red calcium indicator, FRCaMPi, and its soma-localized version, SomaFRCaMPi, are now available from @addgene.bsky.social in various vectors, along with all the sensors used for benchmarking. www.addgene.org/browse/artic...

Apropos of nothing, what is the mood regarding 🧠 #SfN this year? Are people choosing not to travel to the USA? Or are we expecting little change from last year? #neuroskyence

Finally figured out why this lick-port circuit was not working: some absolute idiot mixed up the orientation of a relay on the schematic! (it was me, I made the schematic)

AAVs are crucial vectors for delivering biosensors into neurons! Using AAV delivery, we perform two-color imaging of calcium and potassium transients in neurons. These AAVs are now available from @braincase.bsky.social www.ebraincase.com/news/new-pro...

For anyone wondering: if you need to send a bunch of analog signals around a setup, you can totally misuse ethernet for an easy plug-and-play connection. I've somehow managed to already use all 8 wires for this one, so please, nobody give me any more experiment ideas.

Considering how much I have been using other people's 3D printers over the years, this was probably inevitable

Also, do you *really* need 50+ pages of details for that initial selection? Is it *really* going to come down to which of the candidates wrote a better lab-leadership philosophy statement, just for that first round? Anyone outside academia would consider our hiring process to be completely bonkers.

Open Sesame! The ELT doors have moved for the first time. This was no small feat, as each door will weigh 650 tonnes once completed. The ELT dome & its doors will guard the telescope from the harsh conditions of the Atacama Desert. https://www.eso.org/public/videos/potw2544a/ 🔭 🧪 📹 ESO/ACe

Today is a good day to visit the National History museum in Oslo! Especially since university employees get free access 😎

Strong opening by @mohebial.bsky.social for today's @swebags.bsky.social seminar!

We are looking for a computational postdoc to work with us on new optimisation algorithms to make #RELION even better. Join our bubbly team at the @mrclmb.bsky.social in Cambridge, UK. 🤗 RTs appreciated. mrc.tal.net/vx/appcentre...

It's been a long, long, LONG wait, but the Portrait in Cells scarf - based on this artwork - is back in stock in two weights of silk, yayyyyy! #sciart www.etsy.com/shop/artolog...

Another #FluorescenceFriday image here, from an ongoing project studying circuitry of the retrosplenial cortex. Here we are using rabies to map the inputs specifically to the deep pyramidal cells (L5). Cyan shows the deep cells and magenta shows their presynaptic partners. #NeuroSkyence

Unique opportunity to become a professional sh*tposter*? Count me in! * not professional * they probably don't want sh*tposters

Mouse 🧠 behavior folks: what is the best way to do whisker stimulation? Servos? Magnets? Air-puff? Other? I like the simplicity of servos, but they seem to make quite a lot of noise. That could be fixed with some linkages, but of course, that would increase complexity again.

Updated Matlab to 2025a, and.. what the f*ck @mathworks.bsky.social ? Let me guess: the enshitification will continue until all your customers have jumped ship? It wasn't enough to be down for weeks last year because someone vibe-coded your firewall?

If I had a penny for every time I planned a half-hour meeting and ended up chatting for an hour and a half this week, I'd have two pennies. Which isn't a lot, but it's weird that it happened twice, and I am starting to suspect I may be the problem.

Was this objective expensive?

Pretty Fluorescent Friday by Sierra Turner!

Moving to Norway be like: - Can't sign a rental agreement until I have a Norwegian bank account. - Can't get a bank account without a Norwegian ID number. - Can't get a Norwegian ID number without having a rental contract. It is absolutely hilarious to me how some people think immigration is easy.

Today was grey and rainy; the perfect time to grab a camera and go outside. Please enjoy a little Autumn timeline cleanse!

The program for the 2026 Basal Ganglia GRC is live! 🧠🧪 www.grc.org/basal-gangli... We are already ~60% full, so apply now to join us! Submit an abstract by end of Oct to be considered for a short talk. See you in Tuscany!

Called it. My bet is an optogenetics Nobel in 2027.

Early profs and profs alike: What is your advice for people who are JUST starting their labs? First goals and tasks?

Postdoc Opportunity at Karolinska Institutet: We're seeking an electrophysiologist to join an exciting collaborative project focusing on diabetes and Parkinson's disease. Join us! ki.varbi.com/what:job/job...

Whelp, I did not make the cut. Luckily, I have been given an amazing opportunity elsewhere; and who knows, maybe in a few years things there will be a similar position. But maybe this is a good opportunity to talk about what it's like to apply for academic positions as a postdoc:

I love this sort of thing! Use cheap, generic hardware to do complicated lab stuff!

Advice to US PhD students who might be looking to come to Europe: Contact European PIs early so that you can start working on European Postdoctoral Fellowships early,
