Are gist-like shifts in memory over time evidence of engram transformation? Really? Or partly a general response bias? At #APS2026 in Barcelona this week, Mattia Delmarco will present our work on object typicality and visual memory. psychologicalscience.confex.com/psychologica...

📢 New paper out in @nathumbehav.nature.com: we identify a previously undescribed fast thalamic oscillation (~19–45 Hz) in rare intracranial human recordings that appears specifically during wakefulness and REM sleep — but disappears during NREM sleep. www.nature.com/articles/s41...

We are happy to share our research, recently published in Nature Communication! Using a naturalistic memory task, we show that life events are represented in the brain in different formats, highlighting the flexibility of the memory system. www.nature.com/articles/s41...

Now out in Nature Neuroscience: "Fixation duration on natural scenes is explained by memory encoding not processing demand". www.nature.com/articles/s41... Our eyes don't linger because recognition is hard; they linger to remember. Let me take you on a quick tour. 🧵

New paper with @paulm-k.bsky.social and Mark Stokes on how we switch internal attention between working memory contents. Beta-band oscillations tracked the magnitude and success of these switches. www.jneurosci.org/content/46/1... #neuroskyence

Does the brain perform inference under pressure? Our fMRI study led by Kai Schueren shows acute stress impairs our ability to link memories of past events with new information.🔗 The work is out now in www.science.org/doi/10.1126/... and also covered in www.nature.com/articles/d41...

🔔 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!

New paper out in J. Neuro! We used MEG and pattern classifiers to ask: if a memory is reactivated in the brain, does that mean you'll recall it? Short answer: no. www.jneurosci.org/content/46/1... Read on for the details! [1/7] #neuroscience #memory

We’ve got an exciting new thing to share! We have causal evidence (using TMR) that memory reactivation during sleep promotes abstract understanding of underlying structure, allowing transfer learning in a new domain with zero superficial feature overlap with the learned one.

📣 First paper from the lab! 🎉🧠 Led by brilliant MRes students Aysha and Zhiyun, we found exploring a novel, unpredictable VR environment retroactively enhanced memory in humans: rdcu.be/fc496

Can we really measure replay in humans using MEG with current methods? In our most recent paper we simulated replay under realistic conditions via a novel hybrid approach with astonishing results. we're delighted that it has now been published @elife.bsky.social! elifesciences.org/articles/108...

Nice review by @rhens.bsky.social of the >300 papers using CamCAN data to study the cognitive neuroscience of aging rdcu.be/e73yS - thanks to the authors of all those papers!

How does the brain build a memory? A common assumption is that the neurons activated during an experience collectively form the memory engram. In our new Nature Neuroscience paper (finally out!), we show that this is not the case. www.nature.com/articles/s41...

Every time you experience something new, your brain faces a decision: Should it update an existing memory or create a new one? In our new paper in @sfnjournals.bsky.social #JNeurosci, we isolate that exact decision, moment-by-moment during learning 🧵

I am excited to share my first paper, showing that episodic memory formation is theta rhythmic, is now published in Nature Human Behavior! Check it out here: rdcu.be/e6pzS. Thanks to my PI, Katherine Duncan, and to my collaborators for their support on this journey! Stay tuned for iEEG follow up 🧠

1/9 New paper with @gonzalezgarcia.bsky.social and @lindedomingo.bsky.social : “Characterising semantic prioritisation in visual working memory.” Core question: when we hold visual info briefly in mind, what gets accessed first: perceptual details or semantic meaning?

New preprint 🚨 Across multiple tasks, we show that higher-level info is more readily accessible in WM before evidence accumulation begins. Attention then boosts perceptual detail. www.biorxiv.org/content/10.6... A lot of fun with my colleagues @ckerren.bsky.social and @gonzalezgarcia.bsky.social

Finally: the fantastic #registeredreport from bsky-less Roni Tibon is out: www.nature.com/articles/s41... showing less difference between #episodic vs. #semantic #memory than one might have thought. Proud to have contributed a tiny part to this great paper.

Last week to apply!

Our experiences have countless details, and it can be hard to know which matter. How can we behave effectively in the future when, right now, we don't know what we'll need? Out today in @nathumbehav.nature.com , @marcelomattar.bsky.social and I find that people solve this by using episodic memory.

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 👇 www.nature.com/articles/s41... #neuroskyence

For those into sleep, memory, single units, and neural dynamics this one is for you! New preprint from the fantastic @fabian31415.bsky.social in collaboration with @humansingleneuron.bsky.social exploring how precisely timed sleep rhythms shape memory at the level of single neurons in humans.

Really thrilled that this paper led by @neurozz.bsky.social is now published in its final version in @elife.bsky.social!! This is a memory-focused (as opposed to RL-focused) account of the detailed characteristics of forward and backward awake and sleep replay! elifesciences.org/articles/99931

fMRI signals “up,” but neural metabolism might be going “down.” In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes. rdcu.be/eUPO8 funds @erc.europa.eu #neuroskyence 🧵:

Excited to share our new paper! By combining EEG and eye-tracking, we found that relational memory retrieval is supported by two distinct neural processes across sequential fixations: An early, general theta increase and a target-selective alpha decrease. doi.org/10.1111/psyp...
