It has been a while since @flavioazevedo.bsky.social asked me to take over the Reversals project at @forrt.bsky.social... It has since evolved beyond my wildest dreams, mostly thanks to @aufdroeseler.bsky.social & @lukaswallrich.bsky.social. We are very proud of the Replication Hub & Database ♥️

We just published a paper in PNAS, showing microstructural changes to the hippocampus in aging and presymptomatic Alzheimer's disease - in humans, in vivo. We continue to show the value of structural MRI beyond simply measuring large-scale atrophy! Read here: ow.ly/1NvV50XkXnX

Very excited to share @landrybulls.bsky.social's 1st lead-author preprint in my lab! Using datasets from MySocialBrain.org we measured people's beliefs about how mental states change in intensity over time, the dimensional structure of those beliefs, and their correlates: osf.io/preprints/ps... 🧵👇

🧠 Interested in how the brain constructs and uses meaning? 
In my Journal Club piece for @natrevpsychol.nature.com, I summarize the Controlled Semantic Cognition Framework by Lambon Ralph et al. — a leading model of how the brain represents and flexibly applies semantic knowledge. 👉🏼 rdcu.be/eE31i

Some scientists haven't yet internalized the "why" behind science writing for the public - not just as a service, but for themselves. (I didn't always get it). In this piece for @natrevneuro.nature.com, I draw on the neuroscience of curiosity & decision making to unpack its value. rdcu.be/eCGr7

This was a fun paper to write, and one that fits nicely with some recent work I've been doing on the role of counterfactual simulation in memory encoding. link.springer.com/article/10.3...

The OHBM Open Science SIG is looking for new leadership! Self-nominations are now open! If you're passionate about open science in neuroimaging, get involved. Multiple roles are available, with nominations reviewed in rolling rounds through October. ossig.netlify.app/elections/

✨️Excited to share my first paper is out in Behavior Research Methods with @rjbinney.bsky.social and @pennypexman.bsky.social! We quantified the association of a word's meaning with reward, showing that it is a dimension relevant to semantic processing. 📄🔗Link: rdcu.be/eyqvn

Finally published: “Top-down and bottom-up neuroscience: overcoming the clash of research cultures” www.nature.com/articles/s41... Looking for ways to better understand different neuroscientific perspectives and enable productive collaborations

🧠 Just out with @pennypexman.bsky.social “Simulation in the ‘Blind’ Mind”. We found that even without conscious imagery (aphantasia), people still simulate sensorimotor info when processing language. 💭🔤

Tired of mismatched brain maps? 🧠 The Network Correspondence Toolbox (NCT) brings consistency to neuroimaging by aligning findings across atlases. A big leap toward reproducible brain science! @lucinauddin.bsky.social www.ohbm-com.com/brain-bites/... #OHBM2025 #BrainBites #neuroscience

Proud to be an alumnus of the Bangor Imaging Unit 🎓 The knowledge and skills I gained over four years there shaped my career and how I approach 🧠 research. Amazing to see the work the team has been doing since I graduated in 2023—still raising the bar for neuroimaging in Wales and beyond! 🚀

Here's a 🧵 on a new pre-print with @amyqixx.bsky.social giving fMRI evidence that retrieving a concept leaves a unique neural fingerprint: Semantic memories carry a trace of how they were last accessed, detectable during later recognition. www.biorxiv.org/content/10.1...

When I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary 🧠 www.nature.com/articles/s41...

I’m extremely excited that this work of 3 years is finally published in @braistimjournal.bsky.social. Using condition-and-perturb TMS with e-field-based optimized targeting and dosing, we provide causal evidence for hybrid theories of semantic cognition: www.researchgate.net/publication/...

The first of many papers from the Memory and Forgiveness project is now out at the Journal of Experimental Psychology: General. Led by the indefatigable Gabriela Fernández Miranda, and with Matt Stanley, Sam Murray, and Leonard Faul, we systematically explored differences (1/n)

I’m thrilled to share my new paper on impression formation & updating in @natrevpsychol.nature.com! In it, I argue that impression formation is fundamentally a learning process. And as such, theories of impression formation should be based on mechanisms of learning and memory. Some key take-aways:

🧠✨How do we rebuild our memories? In our new study, we show that hippocampal ripples kickstart a coordinated expansion of cortical activity that helps reconstruct past experiences. We recorded iEEG from patients during memory retrieval... and found something really cool 👇(thread)

🚨 New paper out in Human Brain Mapping! 🚨 with @pennypexman.bsky.social and @rjbinney.bsky.social 🧠 We show that the anterior temporal lobe (ATL) semantic hub supports abstract verb processing—with distinct activity patterns for: • Emotional verbs • Mental verbs • Non-embodied verbs

🧠 How do semantic and executive control dissociate in the frontal lobe? Applying TMS to IFG and pre-SMA, we find: ⚡ Specialization ▸ IFG = semantic (and executive) control ▸ pre-SMA = executive functions 🔄 Compensation between both regions during single-site disruption!

New meta-analysis on reading in the brain by @sabrinaturker.bsky.social, Beatrice Fumagalli, @gesahartwigsen.bsky.social and myself. We looked for consistent activations across multiple levels - from letters to words to sentences to and text reading. www.sciencedirect.com/science/arti...

New preprint ✨ w/ @olafhauk.bsky.social and Matt Lambon Ralph @mrccbu.bsky.social @cambridgeuni.bsky.social @gatescambridge.bsky.social The anterior temporal lobe (ATL) seems crucial for both semantic memory and semantic composition. How to make sense of this neuroanatomical alignment? 🧠 🧵

🚨 NEW PAPER 🚨
We show that concrete (e.g., FLAG) and abstract (e.g., DEMOCRACY) concepts differ not just in the info they contain (e.g., sensorimotor, affective, social, linguistic) but in how these conceptual dimensions interrelate. 🔗 Link: rdcu.be/eb53b

It's finally here! Use the Network Correspondence Toolbox to help contextualize your neuroimaging findings 🧠

It’s out! Our article in Nature Human Behavior led by Yin Wang on the conceptual structure of human relationships across cultures and time. This work is breathtaking nam10.safelinks.protection.outlook.com?url=https%3A...

🚨 NEW PAPER 🚨
We show that concrete (e.g., FLAG) and abstract (e.g., DEMOCRACY) concepts differ not just in the info they contain (e.g., sensorimotor, affective, social, linguistic) but in how these conceptual dimensions interrelate. 🔗 Link: rdcu.be/eb53b

🚨 🧠 We have a new preprint out where we studied which brain networks are engaged during mental imagery and self-generated thought. We used a precision fMRI approach along with multidimensional experience sampling (mDES) to get trialwise self-reports from each participant about what they imagined.

New paper alert! Have you ever looked at single-trial fMRI activation maps? If so, you know that they are super variable. Here we show that the variability is not just noise. In fact, the same task can consistently elicit different activation patterns. www.nature.com/articles/s41...

Finally published in JoN @sfnjournals.bsky.social. In this project, I worked with John Duncan, Beth Jefferies & Matt Lambon Ralph on the gradient structure of the prefrontal cortex. We used various decoding methods to explore its representational landscape (1 of 3) www.jneurosci.org/content/45/6...

🗣️ Language is widely distributed throughout the brain 🧠 In a recent correspondence in @natrevneurosci.bsky.social, we suggest that there is no 'language network' in the brain. What appears as such is an inevitable illusion created in part by the methods we use. www.nature.com/articles/s41...

I think this is a very powerful example of how 'the language network' comes about (or doesn't). See our paper on why we think 'the language network' is widely distributed in the brain: pure.mpg.de/rest/items/i... (same pic of simulation posted below w/ white background for those who use dark mode)

Out in @natureneuro.bsky.social today 🥂 Cytoarchitecture, wiring and signal flow of the human default mode network Combining 3D histology, 7T MRI, and connectomics to explore DMN structure-function associations Led by Casey Paquola, @themindwanders.bsky.social & a terrific team of colleagues 🙏

Are psychometric networks sufficiently supported by data such that one can be confident when interpreting its results? We analysed 294 psychometric networks from 126 papers with the Bayesian approach to address this question @jmbh.bsky.social Sara Ruth van Holst @maartenmarsman.bsky.social 🧵

We “grasp” word meanings: Evidence that individual differences in motor imagery are related to judgments of word meaning, in this new paper lead by Emiko Muraki:

📊 I was involved in launching THINGS-data, containing thousands of fMRI, MEG, and behavioral responses to objects. We show how these can be used to test hypotheses about object vision and semantics. Very proud to have contributed! 💪 elifesciences.org/articles/82580 (5/6)

🚨 New paper out with @samnastase.bsky.social and @haxbylab.bsky.social! We use representational similarity analysis to test how well behavioral, semantic, and visual models capture cortical representational geometries when viewing naturalistic action videos: doi.org/10.1101/2024...

Clever study that explores the debate between those who claim that color categories are 'innate' and those who argue that they are dependent on language. It turns out that monkeys, unlike humans, do not have consensus color categories, suggesting cognitive mechanisms such as language are required.🧪🧠

Five years in the making: our meta-analysis of 10 fMRI datasets across Asia, Europe, and North America (N=2,433). We find creative ability emerges from dynamic switching between default and executive brain networks, with optimal creativity at a "sweet spot."
