Methods: I evaluate and develop EEG/MEG source estimation procedures for connectivity and pattern analysis as well as multi-modal imaging, and apply novel approaches to EEG/MEG analysis to study cognitive variables and tasks. My recent focus has been on developing multidimensional connectivity methods for EEG/MEG analysis, and the co-registration of eye-tracking and EEG to study natural reading behaviour. Reading and semantics: How are the complex computations underlying reading behaviour implemented so efficiently and flexibly in our brains? I address this question using EEG, MEG and fMRI to study effects of psycholinguistic variables/tasks on the human brain response, in combination with behavioural measures (such as eye movements) and in the context of computational models of reading. In particular, I attempt to characterise the spatiotemporal dynamics of brain activity in networks underlying semantic cognition.
