How does an intense event change what we remember about the rest of our day?
Our recent study (N=285) challenges the idea of a uniform emotional memory boost. We found that individuals split into two distinct modes of organizing threat-relevant information.🧵

Now out in Nature Neuroscience: "Fixation duration on natural scenes is explained by memory encoding not processing demand".

Our eyes don't linger because recognition is hard; they linger to remember. Let me take you on a quick tour. 🧵
New paper in Imaging Neuroscience by Olivia R. Christiano and Sebastian Michelmann:
Reliability and signal comparison of OPM-MEG, fMRI & iEEG in a repeated movie viewing paradigm

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.

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

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.

🧵 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.
📢 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.

🔔 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 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.

Flexible prioritization in working memory (WM) is supported by neural oscillations in frontal and sensory brain areas, but the roles of different oscillations remain poorly understood. Recordings in h...
