So proud of Summer! I'm sure she will continue to excel in @asinclair.bsky.social's lab!

Weβve got an exciting new thing to share! We have causal evidence (using TMR) that memory reactivation during sleep promotes abstract understanding of underlying structure, allowing transfer learning in a new domain with zero superficial feature overlap with the learned one.
Super excited to share this preprint! How do we disentangle underlying structure from the particular features of a learning episode to benefit future learning? We find that memory reactivation during sleep promotes this structure abstraction process.

I wish I could tell all the young eager people who write to me about wanting to do research, or the new novel exciting theory they have developed, that if your email (or worse, theory) was very obviously generated by chatGPT it will be very hard for anybody to take you seriously.
Can we really measure replay in humans using MEG with current methods? In our most recent paper we simulated replay under realistic conditions via a novel hybrid approach with astonishing results.
we're delighted that it has now been published @elife.bsky.social!

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
And a sneak peek at a paper that is under review & will be preprinted soon (check this space). Sarvia Aquino Argueta found that reactivation during sleep segregates fMRI neural representations of contextually bound memories from one another, effectively leading to decontextualization. 12/12
Matthew Cho set out to examine whether reactivating a memory once or multiple times during sleep would yield different outcomes. Although we didn't find a TMR effect, we found some evidence for a benefit of multiple cues relative to a single one. 11/12
In our most recent preprint, Neda Morakabati trained classifiers to distinguish between words and images of different categories (during wake). This methods paper (and the dataset) should be helpful for any of you deciding which type of stimuli you should use in your sleep/wake decoding study. 10/12
Back to sleep: Andrew Lazarus examined the temporal dynamics of single reactivation events by interfering with reactivation shortly after its onset, but found little evidence that long reactivation windows are more beneficial than short ones 9/12
And now for something completely different: @dpagliaccio.bsky.social, @dgrijseels.bsky.social & I surveyed >400 LGBTQIA+ neuroscientists worldwide, demonstrated that social, institutional, and political climates shape their experiences and careers, & exposed the unique challenges they face. 8/12
@amirtal.bsky.social and I argue that the literature on awake reactivation is mixed because the extent of processing is rarely measured or manipulated. Elaboration and rehearsal, memory suppression, and nonconscious processing all have different consequences and should be evaluated separately 7/12
Side note: both Gautam & Gayathri found a sustained sigma decline starting after odor onset and lasting well after odor offset. We're still puzzled by these results (using two different setups in two different universities). 6/12
Gautam Narayan was unable to replicate the TMR effects of Rasch (2007) within participants, perhaps because benefits generalized across the learning context rather than impacting a single set of memories 5/12
Gayathri Subramanian (now a lecturer at @arizonastateuni.bsky.social) discovered that when sounds and odors linked to distinct tasks are co-presented during sleep, this nullifies their targeted benefits, suggesting that unrelated memories can't be simultaneously reactivated. 4/12
In yet another preprint, Tiange (Summer) Lu collaborated with @alexatompary.bsky.social to examine whether sleep promotes generalization in a large online cohort (N=137). Not only did she not find a benefit of sleep, but some evidence also suggested that wakefulness promotes generalization. 3/12
In this preprint, Xuanyi (Lindsay) Lin shows that during sleep, affective networks are not only engaged, but their activity patterns strongly predict depression symptoms, acting as a biomarker for depression & supporting a model whereby maladaptive negative biases are perpetuated during rest. 2/12

New preprint! Huge data collection feat from Morgan Barnes and analytic prowess from Thea Ng!
Perturbations of aperiodic activity following learning are reversed in nREM resetting the brain by morning. This reset predicts consolidation!

I am very happy to share our latest paper, just published in @currentbiology.bsky.social! In collaboration with Olga Garaschuk's lab, we used in vivo 2P calcium imaging to investigate the role of sleep spindles in the hippocampus. π§ π€
