Here to learn, share, laugh and rant.
We launched this sci-trailer with a previous preprint. It contained a glimpse of our new behavior analysis pipeline, but we removed it during revisions.
The behavioral flow analysis pipeline is now a full story & a new preprint 🧵👇

I miss Twitter.
I was wrong about Mastodon. It's a beautiful idea and it should be the future. But the lack of an effective algorithm is a killer: I don't get the info I need, nor the feedback I seek.
And most of you didn't migrate.
So I come crawling back.
Dammit.

When I got the email yesterday, I sat there and stared for a few min. Then I started crying. I couldn't stop. I cried and I laughed for 30min. I suddenly felt all the pressure that had built up. The sacrifice, the hard work. All the support I got. The fun, the responsibility.
At its meeting of 20 and 21 September 2023 and upon application of Joël Mesot, President of ETH Zurich, the ETH Board appointed five professors and awarded the title of professor three times.

Question for experienced scientists: When a collaborator has generated data for a paper and in the end you remove the data from the paper (b/c the story gets too big or reviewers ask etc.), do the co-authors remain? I'd say yes, but it feels like a slippery slope. Thoughts?

When a student/postdoc helps you review a manuscript, you should tell the editor. Apart from the learning experience, what's in it for the trainees? That's nothing they can show on their CV, right? Am I missing something? I'm trying to help my team get credit for their work...
I just found an early drawing (2019) of the idea to combine optogenetics with transcriptomics, by

@BohacekLab
@SianDuss
Sorry, an honest and surely stupid neuro-101 question: when brain regions like motor cortex increase in size in response to excessive training (e.g musicians), what accounts for the volume increase? Dendritic complexity? Myelination? Astrocytes? All of the above?😳
The most fun stuff first: you wanna know how your favorite gene/protein/transcript behaves in response to acute stress in the hippocampus (HC)? At different time points? In different cell types? Then check out our interactive STRESSOME app!
I sat right next to my daughter and held her hand at the doctor. I felt how she calmed down because I was close to her. A beautiful moment. With her big brown eyes she looked at me and said: "Daddy, you look much older than you are".
P.S.: yes, she's doing fine
OMG, Richard Morris just challenged Hebb's famous rule 'cells that fire together wire together'. He showed memory encoding of hippocampus-dependent memory when hippocampal cells were prevented from firing! AND: look at this video 😊

It's a bit suspicious if the same lab first reports that all the antidepressants bind TRKB receptors directly (Cell paper, 2021, below), and then show that all the Psychedelics do as well (Nat. Neurosci, 2023).
Do experts in this field have an opinion?
Absolutely stunning paper. Cholesterol binds BDNF-TRKB receptors for membrane trafficking. Antidepressants (incl. ketamine) also bind TRKB (site identified!) and enhance CHOL signaling, together bringing about plasticity and antidepressant effects. 🤯🤩
I'm clearly having too much fun preparing a lecture on translational neuroscience. This was the first report that L-Dopa increases DA in the brain, reserpine depletes it. Literally <2 columns in Nature. No stats, no figures. Authors back then were still good for it.
Ah, the good old days, when dopamine was thought of merely as a side-product of noradrenaline production.
Sorry, but reading this intro in a classic paper by Oleh Hornykiewicz made me chuckle:
