Current neuroimaging techniques allow the noninvasive mapping of human brain networks, with progressively better temporal and spatial resolution. In this talk, I will address the critical problem of relating the electrophysiological and haemodynamic correlates of such networks that are mapped using different techniques. I will first overview my research on the combination of multiple functional magnetic resonance imaging (fMRI) methodologies for obtaining physiologically meaningful and reliable haemodynamic measures. I will then talk about the simultaneous acquisition of the electroencephalogram (EEG) with fMRI, with the aim of directly relating electrophysiological and haemodynamic measures of brain function. Overall, these developments should not only help elucidate healthy brain networks, but also contribute to the identification of biomarkers for specific neurological and psychiatric diseases.
