That’s awesome, you coded a digital measuring tape 🤓

In case you need a proxy for head circumference for your #NIBS meshes: pynibs.head_circumference() should do the trick.

🧠 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!

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. ...

Check out our cool new preprint on heart-brain coupling induced by TMS over the DLPFC! ⚡️🧠📈

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...

Had a great and inspiring time at this year’s Dallas Aging and Cognition conference!

Cognition and Plasticity (CoPla) Lab @copla.bsky.social · Feb 24

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

🚨 New preprint!! Using condition-and-perturb TMS, we show that functional interaction between multimodal and modality-specific cortices is causally relevant for conceptual knowledge retrieval: ssrn.com/abstract=510...

Left Inferior Parietal Lobe and Auditory Cortex Jointly Contribute to Sound Knowledge Retrieval

BackgroundConceptual knowledge is central to human cognition. Neuroimaging studies suggest that conceptual processing relies on the joint contribution of modali

Hello world! We are the Cognition and Plasticity (CoPla) lab @mpicbs.bsky.social in Leipzig, Germany. Our lab combines neuroimaging methods (like fMRI) with non-invasive brain stimulation (like TMS) to investigate plasticity in cognitive brain networks.
