Online Now: Neural reactivation supports memory formation when events end

Neural reactivation supports memory formation when events end

Memory routinely transforms continuous experience into discrete episodes that support flexible retrieval. We propose that these structured representations are established via rapid neural reactivation occurring at the completion of an event. A growing body of evidence across tasks and recording modalities shows that event termination elicits rapid reinstatement of recently encoded neural representations. We review findings revealing that end-of-event reactivation is a robust and functionally meaningful phenomenon, describing when it occurs, how it is measured, and which neural signatures characterize it. We propose that neural reactivation at event offsets offers an efficient neural mechanism for stabilizing newly formed traces against interference, binding relational features into a coherent event index, integrating episodes into pre-existing schemas, and preserving temporal continuity across events.

Check out our new paper! 🧠 Me, @xiongbowu.bsky.social and @fuentemilla.bsky.social review how reactivation at the end of events support memory formation and propose it serves multiple functions from preventing interference to helping preserve temporal continuity! ✨ www.cell.com/trends/cogni...

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...

Non-invasive tracking of ripple-like activity during human sleep using MEG

Hippocampal ripples are considered a key mechanism of sleep-dependent memory consolidation. In humans, however, their direct investigation has relied on invasive recordings from patients with epilepsy...

How are memories consolidated during sleep? Excited to share another preprint: hippocampal SWRs route memory content to the cortex via interregional co-reactivation of concept cells, optimized by slow-oscillation–spindle coupling.

How does the brain replay memories during sleep? Excited to share our new preprint, the outcome of an extensive effort led by Johannes Niediek, showing that reactivation of human concept neurons reflects memory content rather than event sequence.

Excited to share our new paper w/ @cibaker.bsky.social in @natcomms.nature.com linking active vision & memory! We provide evidence that gaze reinstatement & neural reactivation are deeply related phenomena that jointly reflect the experiences constructed during recall. doi.org/10.1038/s414... 🧵1/9

🚨 New preprint alert! Excited to share our latest work on alpha/beta activity, eye movements, and memory. Across 4 experiments combining scalp EEG/iEEG with eye tracking, we show that alpha/beta activity directly reflects eye movements, and only indirectly relates to memory. 👇 Highlights (1/7):

📢 New preprint from the lab: We are very excited to report the discovery of an oscillation in the Central Thalamus using rare direct recordings of human thalamic electrophysiology. The novel oscillation is tightly coupled to specific, natural states of consciousness.🧵

🧠🚨 How does the brain represent what we see? Is visual input transformed to form these representations in similar ways across people and even AI models like DNNs? We explore these questions using fMRI and large-scale representational alignment analyses. 🔗 arxiv.org/abs/2507.13941 Thread👇 (1/8)
