Our paper "Neural timescales from a computational perspective" is finally out in @natneuro.nature.com: www.nature.com/articles/s41... We discuss how computational models and methods can distill empirical observations on neural timescales into quantitative, testable theories of brain computation.
Neural timescales from a computational perspective - Nature Neuroscience
This review integrates computational approaches to provide a unified view on how data analysis methods, biophysical mechanistic models and machine learning approaches can help to uncover the origins a...

The first preprint of the UNSTOPPABLE @mahveenmubarak.bsky.social ! What an “unpredictable” ride it has been and I’m excited (and a bit scared) for what she is gonna discover when she “starts” her graduate program this fall!
What if simply predicting an event could trick your brain into remembering it as real, even when it never happened? 🧠 Very excited to share my very first preprint with @keisukefukuda.bsky.social, born from a question that seemed almost too counterintuitive to be true🧵 1/7 doi.org/10.31234/osf...
I'm starting a lab at the University of Notre Dame! 🎉🍀🧠 Doors open Jan 2027. I'm most excited to meet my future students (recruiting psych grad students for 2027!), help grow a budding neuroscience area, and head home to the midwest after many years away. Please reach out! @notredame.bsky.social
How can aesthetic pleasure be shaped by so many visual attributes: prototypicality, fluency, complexity, symmetry, and self-relevance? I argue that aesthetic pleasure emerges from a balance between categorization-based rewards and metabolic costs of neural activity. doi.org/10.1016/j.co...
“Design can be informed by user preferences, and research can benefit from more ecological validity, from actually being in a space,” says @dirkbwalther.bsky.social @utoronto.ca. “This is potentially game-changing.” 🗼 www.psych.utoronto.ca/news/neurosc...

For the first time in many years our lab won't attend @vssmtg.bsky.social. We don't feel safe and welcome traveling to the USA at the moment. We are attending CSBBCS and @ecvp.bsky.social instead. We are sorry to miss our friends and colleagues at VSS! Hope to see you in Seattle next year!
Day 1 at @iaea-jena2026.bsky.social has been a blast! 3x talks from our group - facial aesthetics, a new inclusive measure of aesthetic engagement, and harnessing the power of AI to assess qualitative responses. Today - catch @hannahmerseal.bsky.social’s talk in the “Aesthetic Brains” session 🧠🎨
TASC 2026 was a big success! Thanks to invited speakers Kalina Christoff Hadjiilieva @psych.ubc.ca and Gerald Cupchik @utsc.utoronto.ca for their interesting presentations and David Rokeby @utoronto.ca for the Voice Scroll installation. www.linkedin.com/feed/update/... @uoftpsychology.bsky.social

Our brains cling to stability: when scenes slowly change, people still see the original for longer than expected. This AI-image study shows that perception lags behind reality -our minds favor continuity over constant reprocessing. doi.org/10.1037/xhp0... @uoftpsychology.bsky.social

Excited that this work with @serences.bsky.social and @timbrady.bsky.social is now out! Our Gabor-wavelet model better predicted voxel responses in scene regions than 3D models. Does this mean that scene areas aren’t “for” processing 3D scene structure? NO, we argue. 1/ dx.plos.org/10.1371/jour...

What determines the perception of orientations in visual cortex, sharp contours or oriented spatial frequencies? It's the contours, the building blocks for shape. Brilliant paper by Seohee Han out in Scientific Reports: www.nature.com/articles/s41... @uoftpsychology.bsky.social

Why do we find some scenes more aesthetic than others? For my first in @sciencenews.bsky.social, I wrote about a new study that suggests that our aesthetic preferences could have evolved as cognitive shortcuts. 🧠🧪 www.sciencenews.org/article/brai...

Dimensionality reduction may be the wrong approach to understanding neural representations. Our new paper shows that across human visual cortex, dimensionality is unbounded and scales with dataset size—we show this across nearly four orders of magnitude. journals.plos.org/ploscompbiol...
