Ever wondered how the hippocampal cognitive map is read-out? @changmin-yu.bsky.social @zilong-ji.bsky.social with Jake & John, show that, during navigation, theta sweeps indicate remembered goal-directions (cf. current/next movements or perceptual targets) 1/2 www.nature.com/articles/s41...

New preprint! We show low arousal states promote hippocampal ripple genesis in sleep and wake. This bridges rodent work, where ripples predominate during sleep, with human studies reporting ripples during active behavior, identifying low arousal as a common mechanism www.biorxiv.org/content/10.6...

🔔 Our new preprint is out! Here we asked whether sleep spindles - a hallmark NREM rhythm linked to plasticity and memory - changes how well latent working memory representations can be accessed after a nap.

Sleep spindles enhance latent working memory representations https://www.biorxiv.org/content/10.64898/2026.06.26.734777v1

🧵 How does the human brain turn experiences into memories? During my four years of PhD at Oxford, I investigated this question through a collaboration between Oxford, Toulouse, and Paris, recording directly from the human brain during a relational memory task.

🔔 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!

I'm proud to say we are releasing LAION-fMRI, a densely sampled 7T fMRI dataset of natural images, with very broad stimulus sampling for testing countless hypotheses and for deeply exploring brain representations. The dataset is now available at laion-fmri.hebartlab.com What does LAION-fMRI offer? 🧵

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

In this Article, Paluch et al. show that unattended working memory items, as well as attended ones, are encoded in persistent activity in the medial temporal lobe. @jankaminski.bsky.social www.nature.com/articles/s41...

How does our brain learn that thunder follows lightning? We don't just remember two separate events; we build a predictive model to anticipate the world. My research dives into this very question: how we learn and predict the order of events. 🧵👇 1/9 #neuroscience #memory #sleep

How does sequence learning reshape item representations? We found that the brain incorporates high-level successor representations even outside the sequence task. This process is supported by slow-wave sleep. Great work by @xianhuihe.bsky.social and the team! www.biorxiv.org/content/10.1...

Hi Bluesky! First post here. Kicking things off with a new preprint. 🧠 Using human iEEG + pharmacology, we asked: is hippocampal theta required for retrieval? Turns out it’s not. Instead, it may reflect a reinstated encoding mode. Thread below. www.biorxiv.org/content/10.1...

🚨new paper alert Blind mice use stereo olfaction, comparing smells between nostrils, to maintain a stable sense of direction. Blocking this ability disrupts their internal compass. Kudos to @kasumbisa.bsky.social! Another cool chapter of the Trenholm-Peyrache collab😉 www.nature.com/articles/s41...
