If you're at @ecvp.bsky.social, check out @dotproduct.bsky.social's poster in today's morning session! Poster T2AM6, "Content-specific and raw occipital alpha oscillations serve distinct functional role in predictive visual perception" #neuroskyence

The hippocampus sits at the interface of perception & memory, allowing us to link past, present, & future through its role in generating predictions. Excited to share this theme issue in @royalsociety.org's Philosophical Transactions B, co-edited with @barense.bsky.social & @mariamaly.bsky.social

Hello hellooo! Come work with us! Check out these open positions with the fantastic @peterkok.bsky.social at @imagingneuroucl.bsky.social. Not that I'm biased, but working with Peter was one of the best experiences of my PhD. The projects look dead fun, almost makes me wish I hadn't graduated!

I am recruiting a postdoctoral researcher and a PhD student, funded by a new ERC grant. The grant focuses on the role of the hippocampus in visual perception, using 7T fMRI (hippocampal subfields, cortical layers) and MEG+iEEG. The intended start dates for both positions are in early 2027. 🧠🟦 1/3

Alpha Oscillations Track the Projection of Reactivated Memories into Conscious Awareness

JOB ALERT: PhD opening in my lab! @cimecunitrento.bsky.social in Italy, as part of an Italian FIS3 starting grant. The project will use advanced analysis methods of MEG data to investigate how our world's naturalistic hierarchical structure facilitates predictive neural processing.

happy to announce the official release of my first R package on CRAN! 🎉 building on the Hmetad toolbox by @smfleming.bsky.social, the hmetad package allows users to fit the meta-d' model of confidence ratings using a familiar brms/lme4-style formula syntax

Excited to share that our MEG project is now out in Current Biology! We show how visual content codes relate to motor oscillations in telling time. Huge thanks to Quirin Gehmacher, Peter Kok, Matt Davis and Clare Press (bsky links below).🧵 authors.elsevier.com/sd/article/S...

🚨Pre-print of some cool data from my PhD days! doi.org/10.1101/2025... ☝️Did you know that visual surprise is (probably) a domain-general signal and/or operates at the object-level? ✌️Did you also know that the timing of this response depends on the specific attribute that violates an expectation?

@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. 🧠🟦 🧠🤖
