About me

I am a postdoctoral researcher in the Stockholm Cognition Lab at the Psychology Department of Stockholm University. I am studying neural processes underlying multitasking.

I obtained my PhD in cognitive neuroscience in 2016 under supervision of prof. dr. Ivan Toni, at the Donders Institute for Brain, Cognition and Behaviour, Radboud University Nijmegen, the Netherlands. In this project I investigated how brain regions in the ventral and dorsal visual stream contribute to the planning of goal-directed actions.

 

Research

I am interested in neural processes underlying planning and coordination of goal-directed actions. These can be actions executed by single actors, but also in cooperative joint action settings. The latter requires understanding of observed actions executed by others, as well as predicting their outcomes.

In my research I make use of behavioural measures such as movement tracking, functional and structural neuroimaging techniques, and brain stimulation.

    The extrastriate body area (EBA) processes visual information about body parts, and it is considered one among a series of category-specific perceptual modules distributed across the occipito-temporal cortex. However, recent evidence raises the possibility that EBA might also provide an interface between perception and action, linking the ventral and dorsal streams of visual information processing. Here, we assess anatomical evidence supporting this possibility. We localise EBA in individual subjects using a perceptual task and compare the characteristics of its functional and structural connectivity to those of two perceptual areas, the lateral occipital complex (LOC) and the fusiform body area (FBA), separately for each hemisphere. We apply complementary analyses of resting-state fMRI and diffusion-weighted MRI data in a group of healthy right-handed human subjects (N = 31). Functional and structural connectivity profiles indicate that EBA interacts more strongly with dorsal-stream regions compared to other portions of the occipito-temporal cortex involved in processing body parts (FBA) and object identification (LOC). These findings provide anatomical ground for a revision of the functional role of EBA. Building on a number of recent observations, we suggest that EBA contributes to planning goal-directed actions, possibly by specifying a desired postural configuration to parieto-frontal areas involved in computing movement parameters.
