Happy to share a new preprint in which @paulbuerkner.com and I introduce a novel model-based approach for precisely estimating the onset and offset of M/EEG effects!

Precise temporal localisation of M/EEG effects with Bayesian generalised additive multilevel models

Time-resolved electrophysiological measurements such as those obtained through magneto- and electroencephalography (M/EEG) offer a unique window onto the neural activity underlying cognitive processes...

The first publication of the #ERC project ‘LaDy’ is a fact and it’s an important one I think:

We show that word processing and meaning prediction is fundamentally different during social interaction compared to using language individually!

POSTDOC Opening: I'm hiring a postdoc to work with me, @ayeletlandau.bsky.social, and Yuval Benjamini on a 4-year NSF funded project to understand timing and memorability in the visual system. fMRI, EEG, eye-tracking all included.

If interested, please DM or email me for more information!

Martin Wiener @martinwiener.bsky.social · Aug 26

Thanks to NSF and BSF, we've received a CRCNS grant!! 🎉

I'll be working with the amazing @ayeletlandau.bsky.social and Yuval Benjamini to explore and understand how our sense of time and image memorability are linked. ⌛🧠

We have 2(!) post-doc opportunities available - details coming soon!

🧠 Why do some brains age faster than others?
🧬 Our new Nature Aging study of over 56,000 participants explores the genetics of the “brain age gap” — the difference between your brain’s biological and chronological age.

Genome-wide analysis of brain age identifies 59 associated loci and unveils relationships with mental and physical health - Nature Aging

This genomic study of magnetic resonance imaging-based brain age in 56,348 people identifies 59 genetic loci, links brain aging to mental and physical health, and suggests high blood pressure and type 2 diabetes as causal factors of brain aging.

Imagine an apple 🍎. Is your mental image more like a picture or more like a thought? In a new preprint led by Morgan McCarty—our lab's wonderful RA—we develop a new approach to this old cognitive science question and find that LLMs excel at tasks thought to be solvable only via visual imagery. 🧵

1/ Why are we so easily distracted? 🧠 In our new EEG preprint w/ Henry Jones, @monicarosenb.bsky.social and @edvogel.bsky.social we show that distractibility is associated w/ reduced neural connectivity — and can be predicted from EEG with ~80% accuracy using machine learning.

detection d' is generally overestimated, coz we tend to be too lazy to collect the necessary data in order to correct for the unequal variance between target present vs absent distributions. turns out we can do this for free - using reaction times data. so, let's do it~

Although our preprint is framed around M/EEG data, the general approach is equally applicable to other commonly used time-resolved signals (e.g., pupillometry, eye-, finger-, or mouse-tracking, EMG, etc).

How does the brain decide? 🧠

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.
