📢 new preprint from the lab on action-guided memory reactivation lead by the fabulous @julia-sc.bsky.social see thread 👇

Episodic memory forms through action: gaze shifts sequentially sample experience as it unfolds 👀🏞️ 🧠 But actions may also help organize how the brain reactivates episodic memories! 👀🧠💭 🏞️ Check out our new preprint 👇 doi.org/10.64898/202... 🎉 @tobiasstaudigl.bsky.social & Aditya Chowdhury 👇🧵

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.

Breathing sets the timing for memory processing during sleep! In our new preprint, precisely shifting memory cues within the respiratory cycle changed oscillatory coordination, memory reactivation and next-morning recall. Fabulous work by @estebanbt.bsky.social, with @tobiasstaudigl.bsky.social!👇

Summer Preprint Alert 🔥🚨 Breathing isn't just for oxygen; it’s a rhythmic pacemaker for the sleeping brain. Our new preprint shows that the respiratory cycle actually gates memory reactivation during NREM sleep! 🧠😴💨 👇🧵(1/8)

Hippocampal ripples initiate cortical dimensionality expansion for memory retrieval - Nature Communications

How past experiences are reconstructed from memory remains unclear. Here the authors used intracranial EEG to show that hippocampal ripples reshape the geometry of cortical representations, supporting...

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 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.

🚨 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):
