Happy to share some of the work done in our lab in this mega-thread of nine (!) papers/preprints (+1 sneak peek) from the last six months. Here goes (in no particular order)! **Please repost** and let me know if you need access to any of the PDFs! #sleeppeeps #sleep #neuroscience 1/12

What happens to memories over time? And what does sleep have to do with it? 🧠 💤 Excited for a lively (perhaps controversial!) discussion at MDRS with @eitans.bsky.social, Gina Poe & @agilboa.bsky.social! I'll share my perspective on why memories (and their neural ensembles) keep changing. Join us!

📣 Inclusive electroencephalography – a tutorial and media resource 📣 We're proud to announce publication of a tutorial to help make EEG research more inclusive, co-produced with Black and Hijabi students. doi.org/10.3758/s134... @thechbh.bsky.social @uob-sop.bsky.social @unibirmingham.bsky.social

👀 Spatial sequences might be replayed in parallel in the hippocampus. If true it might open a whole new interpretation in the MEG replay methodology results. www.cell.com/neuron/abstr...

Comments due Tuesday! rfi.grants.nih.gov?s=6a2b1c22c3... Here is mine.

I've always felt that I learn best by playing around with things (and breaking them 😅). So I’ve put together a few interactive tools to help NeuroCog bachelor/master students grasp some basic neuroscience concepts. 🔗 www.lindedomingo.com/teaching Thanks @ortiztudela.bsky.social for the idea!

Fully funded PhD studentship investigating sleep’s role in forgetting unwanted memories at my lab at @yorkpsychology.bsky.social, starting in September 2027. Funding includes UK home fees and a 3-year tax-free stipend (~£22K per year). Please share widely www.findaphd.com/phds/project...

FYI to everyone submitting this October NIH cycle You need to re-certify your ScienCV AFTER Sept 26 (tomorrow) for your application or it may not be accepted. Great timing!

A nice real-world look at the sleep–mood relationship: across 1,712 nights with home EEG, Pierson-Bartel et al. found later sleep onset predicted lower positive affect the next day. Sleep timing may matter for mood independently of how well we sleep. buff.ly/iryU8Qc

Another postdoc piece out today in @natneuro.nature.com! 🧠💤 In unimpaired older adults, frontal tau pathology tracked with lonely NREM slow waves that fail to travel — and these waves predicted worse overnight memory. full-text: rdcu.be/jDcgH2sK8VZa @ucberkeleyofficial.bsky.social 🧵👇

Hippocampal CA1 neurons are crucial for sleep-associated memory formation in humans: The role of theta power during NREM sleep https://www.biorxiv.org/content/10.64898/2026.09.02.748785v1

University of California, Irvine (UCI) (@ucirvine.bsky.social) is hiring: Open Rank Professor of Teaching in Statistics #professor #statistics

How long after learning can sleep still reshape a memory? A pre-print from Moyano et al. suggests that targeted memory reactivation during NREM sleep reduced forgetting even when the memories had been learned 24 hours earlier. Exciting news for building learning over time! doi.org/10.64898/202...

Hippocampal stimulation timed to memory reactivation shapes human sleep oscillatory dynamics and consolidation https://www.biorxiv.org/content/10.64898/2026.09.02.748628v1

Interesting evidence that sleep-dependent memory processing may begin before we even fall asleep: Denis et al. found that theta activity during learning predicted later slow oscillation–spindle coupling during sleep, which in turn predicted better memory. doi.org/10.1371/jour...

UC Irvine Cognitive Sciences is hiring! Focus on social cognition, broadly construed. Come be my colleague :) I am not on the search committee but happy to talk about the campus, environment, careers, etc any time. recruit.ap.uci.edu/JPF10411

New paper from the lab! In this project we identified different ripple types and link them to behavior and other sleep oscillations doi.org/10.1093/slee...

This is the most fucked up and immediately harmful policy decision I think I've ever seen in adult trans healthcare in the UK, and that's saying something. The Welsh Gender Service is one of the best in the country. It is widely praised by the patients it helps. That is why it is being targeted.

The registration for the long awaited 2nd Middle Eastern Systems Neuroscience Symposium is now open! We offer amazing talks, exclusive networking opportunities and for lucky ~50 people great dinner with the friends you made along the way. Visit our website to register: www.middleeastneuro.com

end of the summer, time to share some cool recent @elife.bsky.social papers: this *important* study shows how locus coeruleus activity is coordinated with heart rate during sleep, confirming previous work in mice and humans, with a possible role for sleep-dependent memory consolidation

Finally, this has gone a bit under the radar, so I want to highlight it: The social, behavioral and economic sciences directorate (SBE) has simply ceased to deliver grants to many of its subareas. Any topic not specifically OK'd by the Trump administration is receiving zero new awards.

Scoop: For nearly a year, NSF has struggled to make new grants. Now we know that it will not catch up. In fact, NSF will award just 6,100 new grants—a 30% y/o/y decline, itself down from a previous avg. of 11,000+. In fact, the last time NSF awarded so few grants was in the early '80s.

Excited to have Taylor's work with me and Daphna Shohamy out in Open Mind now: even at the end of an event, it's not too late to prioritize it for long-term memory!

A study from Azza et al found that >REM theta and sleep spindle activity after an experimental trauma were linked to fewer intrusive memories over the next 6 days. REM theta was also associated w/ less negative affect a week later indicating a protective role for 😴 ! www.nature.com/articles/s41...

Now out in Learning and Memory! pubmed.ncbi.nlm.nih.gov/42608289/ Fun collaboration with @alexatompary.bsky.social, led by then-undergrad Tiange (Summer) Lu, who just started grad school at Rice, working with @asinclair.bsky.social!

Schaeffer et al. recently used temporal interference stimulation during NREM sleep to increase slow-wave activity—& the effect continued after stimulation ended. Across nights, larger increases were linked to reports of more restorative sleep. Very exciting potential! www.nature.com/articles/s43...

Now out in J Neuro Methods! authors.elsevier.com/a/1ncNe_3m9L... Code, data and materials are also available on OSF.

My paper exploring EEG phase dynamics across sleep and retrieval training has just been published online! This paper summarises the work I conducted with Sebastian Michelmann and Simon Hanslmayr, during my PhD. The paper is open access, so feel free to give it a read🧠 direct.mit.edu/imag/article...

📣New paper! How does the sleeping brain help us to integrate new experiences while managing memories from the past? For his PhD work, @sabbaspoor.bsky.social recorded hippocampal ensembles in freely moving monkeys and found something unexpected. 🧵1/n www.nature.com/articles/s41... 🧪🧠📈👩‍🔬#OpenAccess

***New preprint from the lab*** showing “Generative replay across hippocampal-neocortical circuits”. In sleep we show spiking sequences in V1 (sensory neocortex!) that represent information that has not been directly experienced www.biorxiv.org/content/10.6... @bndu.ox.ac.uk @ndcnoxford.bsky.social

Replay of procedural memory is independent of the hippocampus 👀👀 www.nature.com/articles/s41...

Can we study MTL ripples non-invasively? New preprint! We show that source-resolved MEG tracks ripple-like activity during sleep that: • localizes to the MTL • follows the canonical SO–spindle hierarchy • matches an iEEG benchmark • indexes memory reactivation www.biorxiv.org/content/10.6...

Night-to-night sleep EEG variability over one year: We found that intra-individual night-to-night variation was low for spectral power, sleep duration, N2 and REM sleep; medium for N3 and macrostructure; and high for sleep cycle duration, wake and N1. www.biorxiv.org/content/10.6...

Post-encoding slow-wave amplitude during a daytime nap predicts pattern completion from sparse visual cues https://www.biorxiv.org/content/10.64898/2026.07.17.738149v1

Looking to work with a postdoc. Prior experience with fMRI and computational modeling required, interest in psychiatry desired. Fellowship provides three years salary plus independent travel/equipment funds. Send CV and 2-3 manuscripts (preprints OK).

We tested this idea with a representative large-scale survey, and confirmed that higher dream recall frequency is indeed associated with more frequent dream-reality confusions: osf.io/preprints/ps...

Check out our @royalsociety.org Philosophical Transactions B theme issue, "The role of hippocampal prediction: bridging perception and memory." Thanks to all our fabulous authors, and my co-editors @peterkok.bsky.social and @mariamaly.bsky.social who dreamed it up and kept the train on the tracks.

Very excited to share our new review on C-HORSE, our model of the hippocampus! We think there is very encouraging alignment between C-HORSE proposals and the extant empirical literature, though we also note plenty of areas for further model development. royalsocietypublishing.org/rstb/article...

We're finally getting the tools to study replay in humans. But why bother? What can we learn from it that we don't know from rodent recordings? Our thoughts are now out in a new TICS Forum Great fun writing this w @smfleming.bsky.social + @maritpetzka.bsky.social authors.elsevier.com/sd/article/S...

Yikes

I love, love, love this idea!! Spread the word!

During sleep, neurons in the hippocampus 'replay' past activity patterns. This is thought to underlie memory consolidation 🧠 After a busy day, how does the brain sort out what is worth replaying? 🤔 Check out this preprint 📃 from Tirole, Duvelle and Bendor for answers! doi.org/10.64898/202...
