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? Our thoughts are now out in a new TICS Forum Great fun writing this w @smfleming.bsky.social + @maritpetzka.bsky.social authors.elsevier.com/sd/article/S...

What can we learn from studying replay in humans?

Noninvasive methods are making it possible to study neural replay in humans. Although focused on alignment with rodent findings, human research often …

Interested in human replay and solid methods? Jointly with @skjerns.de we're releasing a benchmark dataset with known ground-truth neural sequences in MEG & fMRI, for developing & validating replay methods. First test: existing methods show similar effect sizes, but room to improve shorturl.at/6TgIr

FASTIMAGES: Validating replay detection methods in human neuroimaging using a combined MEG and fMRI dataset

Studies in rodents and humans using invasive electrophysiology have established that neural replay is a ubiquitous phenomenon in the brain that is associated with a wide range of cognitive functions, ...

💥New paper out! Why do some people generalise threat more than others? We show that anxious people generalise more strongly, even after accounting for perceptual mistakes. A huge (!) thanks to @ondrejzika.bsky.social @nicoschuck.bsky.social and @bernhardspitzer.bsky.social

Anxiety is associated with increased generalisation of threat to similar stimuli. This paper dissociates perceptual mistakes from value generalisation and links stronger value-transfer to trait anxiety. @nicoschuck.bsky.social @ondrejzika.bsky.social www.nature.com/articles/s44...

New publication from our lab! 👀 We found that memory enhancement from PEs depends on the brain's neural state: theta/alpha activity & pre-error reactivation are key. TMS over the superior parietal cortex altered response bias but not PE-related memory effects 💡 👉 www.jneurosci.org/content/45/3...

Prediction Error-Related Memory Enhancement Depends on the Neural State Surrounding the Prediction Error Event

Prediction errors (PEs) can enhance memory for preceding events. While such PE-related memory enhancements are critical for understanding adaptive memory, their underlying mechanisms are not fully und...

Delighted to share our work on replay and successor representations! We find replay during very short task pauses in human visual cortex that is linked to learning SRs & happens when learning is implicit. Study led by @lnnrtwttkhn.bsky.social #compneuro #neuroskyence www.pnas.org/doi/10.1073/...

Replay in the human visual cortex during brief task pauses is linked to implicit learning of successor representations | PNAS

Humans can implicitly learn about multistep sequential relationships between events in the environment from their statistical co-occurrence. Theore...
