How is the organization of brain networks related to cognitive performance? To investigate this question and to experimentally manipulate cognitive performance and brain network topology I use brain imaging techniques, direct brain stimulation and drugs that affect cognitions.
My main research questions are:
- Effects of cognitive drugs largely differ between subjects. Is this variance related to differences in brain network topology?
- Are declines or improvements in performance (due to fatigue or cognitive enhancers) related to changes in brain network integrations?
- Brain networks actively try to overcome network distortions. Are these compensation effects related to changes in brain network topology?
