Natascha Roos

Natascha Roos is a Post-doctoral Research Fellow at Radboud University working in the Language Function and Dysfunction research group under Vitória Piai. Her work investigates neuroplasticity in language processing following brain lesions, utilizing EEG and MEG to track millisecond-scale reorganization of neural networks during language tasks in both stroke patients and healthy subjects.

Her academic credentials include:

• PhD in Cognitive Neuroscience (2019-2024), Radboud University
• MSc in Cognitive Neuroscience (2016-2018), Radboud University
• BA in Linguistics (2013-2016), Goethe University Frankfurt am Main, Germany

Roos specializes in electrophysiological investigations of language neuroplasticity, with core expertise in aphasia rehabilitation, neural oscillations, and context-driven lexical access. Her research examines how sentence context accelerates word production, the role of alpha-beta power decreases in temporal-parietal networks, and cross-session reliability of neuroimaging measures for clinical applications. She employs paradigms like the Concise Language Paradigm (CLaP) to bridge comprehension and production mechanisms.

Her publication record reveals consistent focus on context-guided language processing using multimodal neuroimaging. Recent work demonstrates how constrained sentences facilitate lexical access through left-hemisphere networks, with strong test-retest reliability in MEG/EEG metrics. Key findings highlight dissociable neural circuits for visual versus contextual word production and the potential of oscillatory dynamics as biomarkers for language recovery post-stroke.

Roos collaborates with Vitória Piai, Atsuko Takashima, and Robert Oostenveld within the Donders Institute research ecosystem, contributing to stroke rehabilitation science through rigorous electrophysiological methodology. Her work bridges cognitive neuroscience and clinical aphasiology, with implications for targeted neurorehabilitation protocols.
