Language function and dysfunction lab
At the Language Function and Dysfunction Lab, we study the psychology, neuropsychology, and neurobiology of language in healthy individuals and in individuals with brain damage.
Our approach is bi-directional. On the one hand, we use models from cognitive neuroscience to better understand language function in neurological populations with the goal of contributing to the development of novel diagnostic tools and methods to improve language capacity in patients. On the other hand, we use observations of the breakdown of language and communicative abilities following brain insult to obtain unique insights informative for cognitive (neuro)science models.
We have a strong focus on language production (because, of course, you can’t do it all!), but are also interested in comprehension and, especially, the intersection between production and comprehension. Most of our work is based on behavioural measures, electrophysiology, diffusion-weighted imaging, and non-invasive brain stimulation.
For teaching resources on language production, check Speaking: The free book (chapter). It’s free and at an appropriate entry level!

We will be again at SNL this year (from our homes). Follow the links for more. Matteo will present his work on semantic and phonological context effects using picture-word interference and EEG.
We are excited about participating in and presenting at the International Workshop on Language Production this year (from our homes). Follow the links for more (links will be updated soon).
We are excited about attending SNL this year (from our homes). Follow the links for more. Check Joanna’s poster for exciting findings on the temporal lobe white matter in humans vs chimps.
We are very excited to present at Science of Aphasia. Click on the links to see more. We will update the pages to include more info later. Joanna will give a talk on comparative neuroanatomy of the posterior temporal lobe at the white matter level: chimps vs humans!

Source reconstruction of magnetoencephalography (MEG) has been used to assess brain reorganization after brain damage, such as stroke. Lesions result in parts of the brain having an electrical conductivity that differs from the normal values. The effect this has on the forward solutions (i.e., the propagation of electric currents and …
The biological foundation for the language-ready brain in the human lineage remains a debated subject. In humans, the arcuate fasciculus (AF) white matter and the posterior portions of the middle temporal gyrus are crucial for language. Compared with other primates, the human AF has been shown to dramatically extend into the …
Background: Neurocognition and speech, relevant domains in head and neck cancer (HNC), may be affected pretreatment. However, the prevalence of pretreatment deficits and their possible concurrent predictors are poorly understood. Methods: Using an HNC prospective cohort (Netherlands Quality of Life and Biomedical Cohort Study, N ≥ …
Primary progressive aphasia (PPA) is a clinical neurodegenerative syndrome with word finding problems as a core clinical symptom. Many aspects of word finding have been clarified in psycholinguistics using picture naming and a picture-word interference (PWI) paradigm, which emulates naming under contextual noise. However, little is …
Studies suggest that alpha–beta power decreases index word retrieval in context-driven word production. We recorded the electroencephalogram from patients with stroke lesions encompassing the left lateral-temporal and inferior-parietal regions or left lateral-frontal lobe. Results indicate a critical role for the left posterior, but not frontal cortex, in generating the alpha–beta power decreases underlying context‐driven word production.
Language is typically studied in isolation from memory. We demonstrate that the same neuronal computations used by the hippocampus for memory also subserve online language usage. These findings represent a major step in integrating the studies of language and memory, significantly expanding the role of hippocampal theta oscillations.
Background: Interpersonal discourse particles (e.g., actually, indeed) are linguistic tools that enable speakers to respond to contextual expectations. Yet it is currently unclear from a research or diagnostic perspective to what extent Dutch-speaking persons with aphasia (PWA) can successfully integrate these words into a …
White matter (WM) microstructure has been mainly associated with accuracy of picture naming. However, little is known about how WM properties relate to the timing of picture naming and its underlying electrophysiological activity. Here, we linked diffusion-weighted, electrophysiological, and behavioural data, using time-based …
Language recovery after stroke can be supported by neuroplasticity, but its underlying mechanisms remain poorly understood. Most previous studies have either focused on language comprehension or production and/or relied on hemodynamic measures, with limited complementary electrophysiological evidence. Here, we combined a paradigm …
Cognitive impairment is present in nearly half of young stroke survivors, with about one-quarter suffering from aphasia. Recent studies have explored trajectories of cognitive functioning beyond the acute phase after stroke, the potential mechanisms of post-stroke cognitive impairment, and cognitive rehabilitation strategies informed …
Advancements in studying language and the brain have led to important findings but also heated debates regarding the neurobiological basis of language. Despite ongoing discussions and recognition of some of the problems the field faces, the debate remains unresolved. We believe this is unsurprising as the fundamental causes of the …
