The research of our group focuses on oscillatory neuronal activity and cortical network dynamics in cognitive processes such as attention, perception and memory. Furthermore, we seek to gain a better understanding of pathophysiological cortical network dynamics in patients with neurological or psychiatric disorders. Attention is one of the major cognitive processes, which is often disturbed in neurological or psychiatric disorders. One focus of our research tackles the question how cognitive functions such as attention are dependent on oscillatory neuronal activity. To approach this question we combine electroencephalography (EEG) and magnetoencephalography (MEG) measurements with transcranial alternating current stimulation (tACS), which allows to establish causal links between rhythmic oscillatory activity and cognitive functions. The possibility to drive cortical rhythms directly using transcranial alternating current stimulation allows to test the influence of brain oscillations on cognitive functions such as attention. The focus of this project will be on improving the focality of the electrical stimulation for the modulation of specific neuronal networks underlying attention.
