Ripple oscillations are central for memory and sleep.
But ripple detection in humans remains challenging. Here we introduce a simulation approach in @natcomms.nature.com as common ripple detectors mainly pick up 1/f noise and not genuine oscillations

Check out our new paper! We evaluate what we know (and don't know) about the link between memory consolidation during sleep and next-day learning 👇
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. With the great @tschreiner.bsky.social @humansingleneuron.bsky.social
Well done Pin-Chun! Thanks also to @oxexppsy.bsky.social,

How aperiodic 1/f noise drives ripple activity in human brain and impacts on ripple detections is not fully understood. Here authors show that ripple detections should be driven by the 1/f noise, whic...
Thrilled that my recent paper, Hippocampal Ripples during Offline Periods Predict Human Motor Sequence Learning, was selected for the “This Week in The Journal” highlight! 🤩
Huge thanks to @bstaresina.bsky.social and our collaborators who made this work possible!

Sequential coupling of sleep oscillations enables concept-neuron reactivation and supports information flow across the human hippocampal-cortical circuit https://www.biorxiv.org/content/10.64898/2026.01.15.699122v1
😴 Sleep stabilises old memories and supports new learning. Are these benefits of sleep causally linked, driven by a common underlying mechanism, or largely independent? Our new paper digs into this important question!

🔔 Preprint: “Hippocampal ripples evoke a stereotyped cortical response followed by spindle-mediated network synchronization.”
Combining iEEG+scalp EEG during sleep, we show that hippocampal ripples leave a decodable cortical fingerprint and are followed by brain-wide spindle synchronization!
How do experiences reshape our internal representations of the world? @bstaresina.bsky.social &co show that learning sequential experiences reshapes how the #brain represents what we see; a post-learning nap strengthens these predictive changes @plosbiology.org 🧪 plos.io/4dJGwMC
