The main goal of his 'Neuronal Oscillations' research group is to understand how oscillatory activity shapes the functional architecture of the working brain during cognitive processing. While modulations of alpha band oscillations (8-13 Hz) reflect anticipatory top-down modulation, bottom-up processing is reflected by gamma band synchronization (30-100 Hz). Specifically, the core hypothesize states that neuronal communication is gated by inhibitory alpha oscillations in task-irrelevant regions, thus routing information to task-relevant regions. According to this framework the brain can be studied as a network by investigating cross-frequency interactions between gamma and alpha activity.
The research tools applied by the group include computational modeling, MEG, EEG combined with fMRI, EEG combined with TMS and intracranial recordings. These tools are applied to investigate and interpret data from humans and animals performing attention and memory tasks. Furthermore, the group investigates these mechanisms to understand the basis of attention problems in ADHD patients and the aging population.
