Hypothesizing that low frequency FbEEG recordings correlate to the most active brain network at rest, i.e. default mode network (DMN). We investigated the correlation between the two signals, and we showed how the amplification of vasomotor waves by caffeine alters the resulted correlation. Correlations between FbEEG and resting state BOLD were located in the dorsomedial prefrontal cortex (dMPFC), left superior medial and precentral gyri. Caffeine administration augmented the correlations in dMPFC and more correlating areas were observed in; ventromedial prefrontal cortex (vMPFC), cuneus, lingual, middle occipital, middle temporal gyri and right anterior cingulate. These correlations were reduced after physiological corrections.
