New preprint! We mapped out how ‘diffuse’ predictions affect neural representations. We show predictions reshape the geometric layout of the neural representations by compressing the representational spread and stabilize the neural code by reducing the neural variance during memory encoding.
🚨 New #Review #Preprint 🚨 Veera Ruuskanen proposes a new, concrete framework to understand how and why pupil size 👁️, neural activity 🧠, and behavior 💃 interact. doi.org/10.31234/osf... #psychology #neuroscience #pupillometry #perception
Recent work has shown how vulnerable online survey research is to LLMs. Motivated by this, we examined our online Posner cueing data from Prolific. It's concerning. We now must carefully consider when (or whether?) online behavioral data can be trusted.

Excited to share a new preprint from my lab, with some interesting and surprising results. 🧵 follows

1/4 I’m really excited to share that my first PhD manuscript has been accepted for publication in the Journal of Neuroscience 🎉! Until it becomes available, don’t forget to check out our updated preprint (with some additional insights) #JNeurosci
Have you ever wondered WHY memories fade away? And why some people are good at remembering facts while others suck at it? If so, you would be interested in thew new paper by Yinan Xu, Florian Sense, @van-rijn.org, @chantelpratphd.bsky.social, and myself doi.org/10.1371/jour... 👇 🧪
🚨WHOHOO!! I am happy to share that I received the #ERCStG for my project PRECHRON: The Prefrontal Chronometer for Organizing Working Memory.
I am going to study #neuraloscillations during #workingmemory at the @rug.nl @rug-gmw.bsky.social

Always wondered about whether perception is temporally discrete or continuous ⏱️👀? Stop by poster #67 this morning at #ECVP, where I introduce a simple *continuous* rolling window model that accounts for some classic visual phenomena, like band-pass filtering, visible persistence and postdiction.
🚨 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.
Exactly, their experimental setup was also cool in showing you can do basic experiments with high temporal precision using a low-cost setup. Just an Arduino controller and some LEDs.
Maybe it should have just been an erratum or comment, so the conceptual flaw would permanently linked to the online version of the paper. But in any case, their Stroudian interpretation was recently refuted in a re-analysis by Kelber & Ulrich: www.researchgate.net/publication/...
Postdoc position open in our #workingmemory lab! See here for more info: www.unige.ch/fapse/womcog...
Jelmer Borst and I are looking for a PhD candidate to build an EEG-based model of human working memory! This is a really cool project that I've wanted to kick off for a while, and I can't wait to see it happen. Please share and I'm happy to answer any Qs about the project!

Box and arrow models never made sense to me until now
Our new paper out now in Science explores how neural activity in the lateral entorhinal cortex (LEC) *drifts* over time - and *jumps* at key boundaries - to help organize events in memory.

Large-scale projects run the risk of stifling scientific independence. Instead, let’s explore alternative mechanisms of collaboration, writes @neuralreckoning.bsky.social.

Awesome work! We did some similar work in humans, finding that forgetting speed adapts to temporal contingencies in memory delays (link.springer.com/article/10.3...). I’ve wondered since then how this could be implemented, and these adaptive neural dynamics look like a very promising candidate.

Waarom gaat de tijd sneller als je het naar je zin hebt? In deze aflevering van de podcastserie van Universiteit van Nederland over tijd legt Hedderik van Rijn (@van-rijn.org) uit waarom onze beleving van tijd zo flexibel is. www.universiteitvannederland.nl/podcast/waar...
I'd like to thank my collaborators (@van-rijn.org, @elkanakyurek.bsky.social , Chris Eliasmith, Aaron Voelker, Terrence Stewart) who beared with me all those years!
There's a bunch of other phenomena that our UTC model captures well, such as violations of- and conformity to the scalar property (Weber's law), one-shot learning of intervals, neural responses underlying timing, common capacity limits in WM and timing, and more! Something for everyone! 🎉 (6/n)
