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!

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.

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.

Episodic details are better remembered in plausible relative to implausible counterfactual simulations - Psychonomic Bulletin & Review People often engage in episodic counterfactual thinking, or mentally simulating how the experienced past might have been different from how it was. A commonly held view is that mentally simulating alt...

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/

Super interesting! Congratulations, Irina! 🌟

✨️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.

Looking for ways to better understand different neuroscientific perspectives and enable productive collaborations

We found that even without conscious imagery (aphantasia), people still simulate sensorimotor info when processing language. 💭🔤

Abstract words are hard to acquire: Does social relevance help?

We tested if social experience helps children learn words—analyzing >4,000 words by socialness, valence, and concreteness.

👬 More social words were learned earlier
💭 Socialness particularly helped abstract words, but…

Semantic Memory Traces Reflect How They Were Last Retrieved Episodic memories are known to change with each act of retrieval. We hypothesize that semantic memories are altered in a similar way when retrieval draws on a core dimension of conceptual knowledge: s...

Here's a 🧵 on a new pre-print with @amyqixx.bsky.social giving fMRI evidence that retrieving a concept leaves a unique neural fingerprint:

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/...

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.

🧠✨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

Causal Contributions of Left Inferior and Medial Frontal Cortex to Semantic and Executive Control Semantic control guides the targeted and context-based retrieval from semantic memory. The overlap with and dissociation from domain-general executive control in the frontal lobe remains contentious. ...

🧠 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!
