The individual EEG alpha frequency (IAF) is a potential marker for a persons cognitive abilities. It has been demonstrated that subjects with a higher IAF perform better in working memory tasks. Additionally, there exist resting state networks (RSNs) that are involved in task execution. However, little is known about the functional networks that underlie the IAF. We performed simultaneous EEG-fMRI recordings in 20 subjects and correlated the intra-iondividual IAF fluctuations to fluctuations in the fMRI BOLD signal. The results were spatially compared to RSNs. Our results highlighted a positive association of IAF with RSNs important for attention and working memory.
