From line drawings to scene perception — our new review argues for moving beyond experimenter-driven manipulations toward participant-driven approaches to reveal what’s in our internal models of the visual world. 👁️✍️🛋

Characterizing internal models of the visual environment | Proceedings of the Royal Society B: Biological Sciences

Despite the complexity of real-world environments, natural vision is seamlessly efficient. To explain this efficiency, researchers often use predictive processing frameworks, in which perceptual effic...

Hellohello #ICON2025! Please come and have a chat with me today at 10.45am about some content-specific alpha fluctuations! 🤓

Nadine Dijkstra @nadinedijkstra.bsky.social · 27d

Finally, on Friday at 10:45, we have Imagine Reality Lab affiliate @dotproduct.bsky.social presenting:

P6.36 | Pre-stimulus Shape Predictions Fluctuate At Alpha Rhythms And Bias Subsequent Perception.

Showing how content-specific pre-stimulus alpha-band oscillations influence perception.

At long last, the pre-print to our MEG study + RIFT study and the final paper from my Ph.D with @olejensen.bsky.social We show that strong pre-search alpha oscillations are associated with faster responses in visual search www.biorxiv.org/content/10.1...

Very proud to share this one🥹! We show that personalized signatures of brain activity are heritable and relate to the expression of specific genes. That means my brain-fingerprint is very similar to my twin brother's! #ResearchIsMeSearch🧠 🧬 ♊️

Are sensory sampling rhythms fixed by intrinsically-determined processes, or do they couple to external structure? Here we highlight the incompatibility between these accounts and propose a resolution [1/6]

Beautiful paper by the brilliant @jhaarsma.bsky.social exploring how false and veridical percepts converge and diverge. Turns out both share content-specific and confidence signals; and hellohello pre-stimulus alpha... what are you up to with false percepts?

Hellohello! Come say hi today, 3:00-5:00pm, Banyan Breezeway (16.322).
How does the brain hold onto predictions before something even happens? We show that predicted shape info lives in pre-stimulus alpha-band oscillations (10–11Hz), and biases perception without boosting sensitivity.🧠
