Research while in the Mattingley Lab
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.
