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

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

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

New research from Dr. @omersharon.bsky.social UCBerkeley!

In aging, slow delta waves intrude phasic REM sleep → linked to worse memory consolidation 🧠 & Alzheimer’s pathology.

Suggests REM sleep plays a critical role in memory & brain health.

Can you explain?

Omer Sharon @omersharon.bsky.social · Aug 23

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)

Omer Sharon @omersharon.bsky.social · Aug 23

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)

Fresh results now in bioRxiv! 🎉 We know about the function of NREM sleep for overnight memory consolidation. But what about REM sleep? We found that in aging, slow delta waves can intrude phasic REM periods, and this, is associated with worse overnight consolidation 🧠 (1/5) doi.org/10.1101/2025...

Science doesn’t need to be pretty and go according to plan; it just needs to lead to a discovery. If doesn’t have to be done alone or together with someone else; there just needs to be a discovery. It doesn’t need to happen fast or slow; just as long as there’s a discovery, then everybody is happy.
