Super happy to share my very first first-author paper out in @sfnjournals.bsky.social! We show content-specific predictions are represented in an alpha rhythm. It’s been a beautiful, inspiring, yet challenging journey. Huge thanks to everyone, especially @peterkok.bsky.social @jhaarsma.bsky.social

@dotproduct.bsky.social's first first author paper is finally out in @sfnjournals.bsky.social! Her findings show that content-specific predictions fluctuate with alpha frequencies, suggesting a more specific role for alpha oscillations than we may have thought. With @jhaarsma.bsky.social. 🧠🟦 🧠🤖

I enjoyed reviewing this study. Fascinating you get improved decoding of feedback signalling on memantine while ketamine is thought to disrupt it (both NMDA-ant). Could subtle differences in ketamine and memantine beyond NMDA-ant be relevant to psychosis? (Memantine being much less psychotomimetic)

We show that memantine selectively improves neural decoding of attended illusory Kanizsa triangles, revealing NMDA receptor-dependent enhancement of feedback processing. elifesciences.org/articles/100... Thanks to Samuel Noorman @fahrenfort.bsky.social @timostein.bsky.social Jasper Zantvoord

Just a reminder that Orwell’s protagonist in 1984, Winston Groom, works as a copy editor, except that his job entails endlessly “correcting the data” so that the archival record conforms to the Party’s preferred fictions, and what is “known” becomes a principal instrument of conformity.

Really glad my first MEG paper is out! Orientation-specific sensory signals accompanied falsely perceived gratings, and a shared perceptual confidence code was present on FA and veridical trials. We also found a unique role for increased beta oscillations preceding high confidence FA. Read for more!

Shared and diverging neural dynamics underlying false and veridical perception

We often mistake visual noise for meaningful images, which sometimes appear as convincing as veridical percepts. This suggests considerable overlap between the mechanisms that underlie false and verid...

Our study using layer fMRI to study the direction of communication between the hippocampus and cortex during perceptual predictions is finally out in Science Advances! Predicted-but-omitted shapes are represented in CA2/3 and correlate specifically with deep layers of PHC, suggesting feedback. 🧠🟦

Communication of perceptual predictions from the hippocampus to the deep layers of the parahippocampal cortex

High-resolution neuroimaging reveals stimulus-specific predictions sent from hippocampus to the neocortex during perception.
