How does spontaneous memory reinstatement at rest relate to episodic memory during development? And how do early experiences influence neural mechanisms of episodic memory encoding and reinstatement? New preprint! www.biorxiv.org/content/10.1...

Come work with us! UC Irvine Cognitive Sciences is looking for a new Assistant Professor to join our team: recruit.ap.uci.edu/JPF09896 I'm not on the committee, but happy to talk if you're interested.

🚨 New paper alert! 🚨(1/6) Excited to share our work, out now in Science Advances We show that a rapid norepinephrine surge along a brainstem pathway (LC→PRN) is a key driver of sound-evoked awakenings www.science.org/doi/10.1126/...

Kudos to the Philly Inquirer for actually centering the voices of trans youth and their families. "It's not about protecting the kids. It's about taking away the rights of people who you don't want to exist." share.inquirer.com/TE1hNg

How do the brain’s event representations change as we gain familiarity with an experience? Brain regions’ representations can become coarser or finer as event familiarity increases. Fine-tuning predicts memory recall. Excited to share this work with Narjes Al-Zahli & @chrisbaldassano.bsky.social!

Online Now: Memory editing during sleep: mechanisms, clinical applications, and technological innovations

For >5 years, the International Sleep Replay Workshops (ISRW) have brought together scientists studying sleep & memory. The next ISRW will be on March 6th in Vancouver (before @cogneuronews.bsky.social). Follow the link for details and to join the mailing list. isrw.bio.uci.edu Pls repost! #sleep

Now here’s the really cool part: theory predicts medial temporal lobe (MTL) first stores memories, but cortex is the final storage site. Our models show this after one night of sleep! MTL models decode presleep, while frontal cortex (FC) decodes postsleep, but not vice versa. 5/6

Yes, this is very important! Intentionally rehearsing information, recalling it based on a cue, spontaneously thinking about it, and non-consciously reactivating it are all VERY different things. (I would argue that memory reactivation during sleep sometimes can be conscious too though 🙂). 1/2

New opinion piece! @amirtal.bsky.social and I argue that "wake reactivation" is not a scientifically useful construct; It encompasses nonconscious & conscious processes w/ varying levels of elaboration & diverging consequences, leading to conflicting results authors.elsevier.com/a/1lgli4sIRvW-LQ

New paper in Imaging Neuroscience by Martyna Rakowska, Penelope A. Lewis, et al: Distributed and gradual microstructure changes are associated with the emergence of behavioural benefit from memory reactivation doi.org/10.1162/IMAG...

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...

🚨New Paper🚨 I spend a lot of time trying to control what people dream about. Usually, we are looking at dreams of recent memory. In this new paper, for the first time, we caused people to dream about a specific REMOTE memory from their distant past. #cogsci #psychscisky 🧠🟦

Delighted to share our work on replay and successor representations! We find replay during very short task pauses in human visual cortex that is linked to learning SRs & happens when learning is implicit. Study led by @lnnrtwttkhn.bsky.social #compneuro #neuroskyence www.pnas.org/doi/10.1073/...

"..NIH remains dedicated to fostering open, competitive, and accountable science and supporting investigators as they pursue innovative, and sometimes controversial, questions grounded in rigorous methodology.".....unless you're study anything related to trans people....then you can just fuck off.

Well, it's Fustilarian Friday again and the NIH director does not disappoint with his new Statement of NIH Priorities. Despite a cover letter promising that his has made it his lifelong mission to resists any form of political influence on science, the document includes this abomination.

I'm not a big poster, but had to share how proud I am of my postdoc, Lauri Gurguryan, for submitting the FIRST paper from my lab 🎉 Here, we ask a classic ? Do short- and long-term memory rely on separate or shared underlying stores Checkout the preprint: bit.ly/3Hyyl83 #neuroskyence #PsychSciSky

***🚨 New Paper 🚨*** Both #sleep and eyes-closed waking rest improve memory. But sleep also increases FALSE recall in some paradigms. Q: Does eyes-closed rest similarly increase false recall? A: No. Free access link: authors.elsevier.com/a/1lYgb3qNaA... #sleeppeeps #psychscisky 🧠🟦

Let's please keep the remaining staff at NIH, NSF, etc in our thoughts even as you lose sleep over your own lab and scientific career. They are enduring pure chaos to try to hold the fort. See snapshot from wapo.st/4feKKuu (gift 🔗) saying they are "barely holding it together"

🧠💤 Memory consolidation during sleep is metabolically tuned? Short-term fasting enhances hippocampal ripples, cortical spindles, and slow oscillations, and shifts slow oscillation–spindle phase-amplitude coupling—all without altering overall sleep architecture. 📄 academic.oup.com/sleep/advanc...

Our new episode is out! We talk with @annaschapiro.bsky.social about neural network models, the Complementary Learning System theory and Anna's recent work on testing predictions of neural network models with TMR/EEG Big thank you to Anna for joining the podcast! www.buzzsprout.com/787211/episo...

🧠🔬 This important study demonstrates that slow fluctuations in serotonin release during wakefulness and non-REM sleep correspond to periods of heightened arousal or enhanced offline information processing, especially in the hippocampus. Congrats to the authors! elifesciences.org/reviewed-pre...

In this study, led by BlueSky-less superstar undergrad Andrew Lazarus, we set out to ask whether longer reactivation events during sleep lead to more memory benefits. Results suggest this is not the case, but there are some disclaimers. Read all about it! #sleep www.sciencedirect.com/science/arti...

Excited to share our latest work spearheaded by @anikaloewe.bsky.social & @maritpetzka.bsky.social. 20 min naps increased the chance to solve an insight task if sleep reached N2 stage; but the EEG spectral slope was the best predictor of insight dx.plos.org/10.1371/jour... #compneuro #psychscisky

Last year, Sophia Snipes made a fascinating discovery: a new rhythm in the zoo of EEG oscillations, and one specific of REM #sleep! 🧠🧪💤 Such a claim would need a thorough verification, which is now out: journals.physiology.org/doi/full/10.... Watch this space as Sophia will be pursuing this work!

preprint alert 🚨 1/ Can we accurately detect sequential replay in humans using Temporally Delayed Linear Modelling (#TDLM)? In our recent study, we could not find any replay and decided to dig deeper by running a hybrid simulation with surprising results. Link to preprint & details below 👇

Just out in PLoS ONE: Usually, resting with one's eyes closed after learning improves memory. We thought people with #ADHD might show less memory benefit from rest. We were wrong! But some interesting descriptive data and exploratory analysis, we hope you read it. 😁 #psychscisky #neuroskyence

🚨New in @cellpress.bsky.social We discovered that hippocampal replays in natural-scale environments are highly fragmented, not full-length. doi.org/10.1016/j.ce... 👇🧵

New preprint! How do we integrate new information into prior knowledge? We find that existing knowledge enables rapid new learning but that interleaved replay during sleep promotes integration of new and old information. Modeling suggests a sleep context suppression mechanism. osf.io/preprints/ps...
