New cool preprint by @drsandramartin.bsky.social and her colleagues using dual-site TMS over IFG and pre-SMA during semantic and executive control:
🔍 Key findings: ✅TMS produces a significant site-specific non-linear increase in HBC. ✅Non-linear interplay between stimulation intensity and pain-related side effects, as well as the repeatability of HBC measurements across sessions Check it out and let us know your thoughts! 🚀
Postdoc @drsandramartin.bsky.social presented her research on aging effects on predictive processing in language at the Dallas Aging and Cognition Conference this week. Results show that as we age, we increasingly rely on our internal predictions, possibly as compensation for executive decline. 1/2
Co-authored with Merle Schuckart, @gesahartwigsen.bsky.social, and @jonasobleser.bsky.social. Find the preprint with all the really cool methods (n = 175 + replication!) and insights here: www.biorxiv.org/content/10.1... #PredictiveProcessing #Aging #LanguagePredictions

Thrilled to share our latest research with PhD student @zijianfeng.bsky.social and Postdoc @drsandramartin.bsky.social! We investigated TMS-induced heart–brain coupling (HBC) as a potential biomarker for personalized stimulation targets in the left DLPFC: doi.org/10.1101/2025...
🚨 I'm thrilled to share our new preprint on the representation of taxonomic and thematic semantic relationships in the human brain as a function of task demands and healthy aging: www.researchgate.net/publication/...
Our eye-tracking experiment on cognitive effort modulation by valence and counterfactuality got accepted to #CogSci2025!

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...
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/...
🧠 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!
