Current research

Although specific functional connectivity patterns have been identified in cortical regions associated with brain networks of attention, it remains unclear a) how they represent top-down and bottom-up attention mechanisms, and b) how these brain networks act together to guide selective attention during visual search. I use electroencephalography (EEG) and transcranial alternating current stimulation (tACS) in healthy subjects to study the relation between resting-state functional connectivity and behavioural mechanisms underlying attentional control. The aim is to contribute to a better understanding of how stimulus selection is controlled and implemented in large-scale brain networks.
