And finally I will talk about a large group project in which we show that pupil-size changes alone (independently of external stimuli) trigger retinal responses. dx.doi.org/10.1111/psyp... with @olaf.dimigen.de @hakankarsilar.bsky.social @anavili.bsky.social @veerahelmisofia.bsky.social

We report a previously unknown response in the human retina and visual cortex that is locked to pupil constriction and likely reflects a retinal response to a sudden decrease in retinal light exposur...

Our detailed tests of high-speed OLED monitors for vision, eye-tracking, and EEG research are finally out in 𝐵𝑒ℎ𝑎𝑣𝑖𝑜𝑟 𝑅𝑒𝑠𝑒𝑎𝑟𝑐ℎ 𝑀𝑒𝑡ℎ𝑜𝑑𝑠. So why did it take 1.5 years to publish this? Because we discovered a new property of OLEDs that vision researchers should be aware of... [1]

Everyday visual experience tunes neural processing. Using fixation-related EEG, this new work shows how the N1 preview benefit depends on Chinese readers' prior experience with left-to-right vs. up-down reading. @umaurer.bsky.social www.authorea.com/doi/full/10....

Happy to be a collaborator on this new work by first-author Xin Huang from Urs Maurer's lab. In two combined eye-tracking/EEG experiments, we asked whether rapidly processed magnocellular (M-pathway) information in parafoveal vision plays a special role for word recognition in natural reading. (1/2)
The figure shows exemplary stimuli in experiments 1 and 2, that were biased for M- vs. P-pathway processing by spatial filtering (exp 1) or by isoluminance (exp 2).

Together with recent work by @olaf.dimigen.de on using RIFT with a monitor setup, as well as our own new preprint on using a monitor setup to track attention (www.biorxiv.org/content/10.1...), RIFT is now a lot more accessible both in terms of available recommendations and materials.

Launched in 2023, Imaging Neuroscience is now firmly established, with full indexing (PubMed, etc.) and 700 papers to date. We're very happy to announce that we are able to reduce the APC to $1400. Huge thanks to all authors, reviewers, editorial team+board, and MIT Press.

Academic authors, here's a peek into the black box of journal publishing from an journal editor if you can bear it:

🚨 New preprint: Invisible neural frequency tagging (RIFT) for the underfunded researcher: 👉 www.biorxiv.org/cgi/content/... RIFT uses high-frequency flicker to probe attention in M/EEG with minimal stimulus visibility and little distraction. Until now, it required a costly high-speed projector.

Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.

Are you looking for a precise monitor for vision science, eye-tracking, or EEG? In a new preprint (w/ Arne Stein), we tested a new type of display with excellent performance in time-critical experiments: "High-speed" (240 Hz) OLED monitors. All details here: www.biorxiv.org/content/10.1...
