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...

Hello memory folk! Two dates for your calendar: Symposium submissions open 1st September 2026 Open abstract submissions open 1st November 2026 Start thinking about interesting symposiums and talks now so you're ready to submit your proposals/abstracts when the time comes!

I would like to announce the Cutting Gardens EEG conference, a new global, decentralized, and sustainable way of organizing conferences. This conference is on EEG methodology and analysis pipelines, and it is comprised of different "gardens" around the globe, taking place from Chile to China.

We're finally getting the tools to study replay in humans. But why bother? What can we learn from it that we don't know from rodent recordings?

How do humans keep inventing tools and technologies that no single person could create alone? Our new preprint, led by @anilyaman.bsky.social & @ts-brain.bsky.social shows that semantic knowledge guides innovation and drives cultural evolution. 🧠📘 arxiv.org/abs/2510.12837

🔔 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!
