I couldn't find a tool to plot different #neuroimaging data in one consistent style, so I made one! Meet yabplot (yet another brain plot) - a #Python package for (sub)cortex & tracts.🧠

Still pumped up from yesterday's international sleep replay workshop! Provocative talks, engaging discussion groups & enthusiastic engagement by all attendees from undergrads to full professors. Stay tuned for info on the next one. And now, on to @cnsmtg.bsky.social. Check out our lab's posters!
Save the date for the 1st MEEP – Heidelberg Summer School on Memory and Sleep: May 31st to June 3rd
Keynote speakers: @marwimber.bsky.social @mgarvert.bsky.social & Dan Bendor
Sessions on:
memory processes
sleep & replay
analysis and stimulation techniques

It's still 10 times better during sleep compared to wake. e.g we know pretty well what slow waves are from scalp to cell level.
As for the rest there is no consensus what brain osc are in all levels :)
Never say never :) We will not see place cells. But some papers have shown releveant spatial resoultion that can be used to show memory relevant memory rep. e.g Siclari et al 2017 Nat Neuro
Everyday is a full flight :)
A worm, H. miamia, appears to have a diffuse 'brain' without regional specialization. "Early brains may have arisen through the condensation of diffuse nerve nets into unregionalized brains, with regionalization evolving secondarily." www.biorxiv.org/content/10.1...
Maybe just go back to pen & paper? AI can probably transcribe the handwriting.
Congrats Anna and team, looking fwd to diving in

Sleep colleagues, please submit tonight to be considered for a short talk.
Under Trump, the NIH is giving fewer grants to fewer scientists. The grants awarded are smaller and scientists have less time to spend them.
Projects in cancer, diabetes, aging, neurological disorder, and more are going unfunded.
“Make America Healthy Again.”
Announcing the 5th International Sleep Replay Workshop (ISRW): March 6, 2026, Vancouver, prior to CNS.
Program: poster session, discussion groups, 2 symposia, 7 short talks, & many opportunities to interact.
Register by Dec 19 at isrw.bio.uci.edu
All researchers focused on sleep/cognition welcome.
Registration is open. Please spread the word. The preliminary schedule will be up on the site later this month, and we've got an amazing line up!
Fascinating, the link is broken. Could you pls add a link to the editorial paper? Thx

Why do we remember emotional events so vividly? Our new paper @nathumbehav.nature.com suggests that emotional arousal enhances memory by strengthening integration across large-scale brain networks! Led by the amazing @jadynpark.bsky.social & @ycleong.bsky.social! doi.org/10.1038/s415...

Here’s my Fluorescence Friday highlight: just got this beautiful shot from the locus coeruleus in our latest tissue section! You can see astrocytes (in green) glowing and wrapping around tiny blood vessels (in red), with pTau staining (in magenta) lighting up the scene. It’s wild how much is going on in just one microscopic field—so cool to see these markers all together and think about what they mean for brain health and Alzheimer’s research. Loving the chance to peek into these cellular hangouts each week! #FluorescenceFriday #PhDLife #Neuroscience
For #FluorescenceFriday✨ Exploring the beauty of the locus Coeruleus using IF staining: neurons🔵 surrounded by glowing astrocytes🟢 embracing delicate blood vessels🔴, alongside striking pTau signals💗. A vivid reminder of the cellular complexity shaping brain health and disease. #LC #Neuroscience
Thanks for the shout out!
The preprint is available: pubmed.ncbi.nlm.nih.gov/40894612/
Big kudos to our amazing first author, Tenzin Desel!
We are looking fwd to further improve it in the review process
Please join us and spread the word
👇 #SleepPeeps Please repost to help me spread the word on this study. This is a very big commitment compared to most "online" studies... but I know there are some good participants out there on the interweb who what to help! 🙂👇
Can you explain?
We think it means that there must be something critical for overnight memory consolidation about these phasic REM periods. What may that be? Stay tuned.
Please don’t hesitate to reach out if you have ANY questions or comments on the manuscript (5/5)
Last, we extended the findings to an additional independent cohort (N=558), tying REM sleep changes to genetic AD risk (APOE). (4/5)
Then, we followed the same analysis on a subset from the Longitudinal Aging Sleep Study at Berkeley (N=61), which underwent deep imaging (MR, PET), and a classic overnight paired association memory task. (3/5)
