We’ve 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.

TDLM-Resting-State Simulation How sensitive is TDLM really? Can we actually find replay when we know it is present?

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!

Dorsoventral hippocampus neural assemblies reactivate during sleep following an aversive experience - Nature Neuroscience Synchronization of sharp-wave ripples across the dorsoventral hippocampus during sleep supports coordinated reactivation that represents negative experiences more faithfully than positive ones.

Our paper is out today!!! (not an April fool's day joke) Congrats to authors @azulsilva.bsky.social, @belalima-paiva.bsky.social, Ele Pronier, and mostly to the amazing scientist and human being who led this project @facuumm.bsky.social

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).

@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

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!
