Visual Spatial Attention

This research line combines fMRI and NIBS to study the neural network effects underlying the control of spatial attention. The fronto-parietal networks involved include both the ventral and dorsal attention network and their dynamic interaction during processes of automatic bottom-up and voluntary top-down attentional control. NIBS is used to specifically interfere with various nodes within these networks during endogenous and exogenous spatial cueing, visual detection, and visual search paradigms. A special focus lies on the functional hemispheric asymmetries in spatial attention control and the respective empirical assessment of the opponent processor and hemispheric balance model. The latter has direct relevance for a possible clinical application for the rehabilitation of spatial neglect and extinction after stroke.

This research line is funded by a grant from the European Research Concil (ERC).
