Concurrent EEG and fMRI acquisitions in resting state showed a correlation between EEG power in various bands and spontaneous BOLD fluctuations. However, there is a lack of data on how changes in the complexity of brain dynamics derived from EEG reflect variations in the BOLD signal. The purpose of our study was to correlate both spectral patterns, as linear features of EEG rhythms, and nonlinear EEG dynamic complexity with neuronal activity obtained by fMRI. We examined the relationships…

In this work, we investigated the regional characteristics of the dynamic interactions between oscillatory sources of ongoing neural activity obtained using electrophysiological recordings and the
Aperiodic measures of neural excitability are associated with anticorrelated hemodynamic networks at rest: a combined EEG-fMRI study
These findings suggest that resting-state EEG signals acquired in an fMRI scanner reflect a balance of top-down and bottom-up stimulus processing, even in the absence of an explicit task.
Modeling the Hemodynamic Response Function Using EEG-fMRI Data During Eyes-Open Resting-State Conditions and Motor Task Execution.
A novel methodological approach based on combining distributed EEG source space reconstruction, which improves the spatial resolution of HRF estimation and using block-structured linear and nonlinear models, which enables us to simultaneously obtain HRF estimates and the contribution of different EEG frequency bands is proposed.
Variations in the frequency and amplitude of resting-state EEG and fMRI signals in normal adults: The effects of age and sex
Both fMRI and EEG signals reflect age-related and sex-related brain differences, but they likely associate with different origins.
Comparison of local spectral modulation, and temporal correlation, of simultaneously recorded EEG/fMRI signals during ketamine and midazolam sedation
The utility of simultaneous recording of simultaneous EEG/fMRI is demonstrated: each modality provides unique insights, and combinatorial analyses elicit more information than separate recordings.
How much of the BOLD-fMRI signal can be approximated from simultaneous EEG data: relevance for the transfer and dissemination of neurofeedback interventions.
With this pipeline, a more accurate reconstruction of the BOLD signal can be obtained, which will positively impact the transfer of fMRI-based neurofeedback interventions to EEG setups, and more importantly, their dissemination and efficacy in modulating the activity of the desired brain areas.

EEG-informed fMRI analysis during a hand grip task: estimating the relationship between EEG rhythms and the BOLD signal
A novel method to perform EEG-informed fMRI analysis, so that the EEG regressors take into account both the changes in the spectral profile and the rhythms distinction, and shows that the proposed method better captures the correlations between BOLD signal and EEG rhythms modulations.
Electrophysiological signatures of resting state networks in the human brain
This work has identified six widely distributed resting state networks and supports for the first time in humans the coalescence of several brain rhythms within large-scale brain networks as suggested by biophysical studies.
Electroencephalographic signatures of attentional and cognitive default modes in spontaneous brain activity fluctuations at rest
It is suggested that alpha oscillations signal a neural baseline with “inattention” whereas beta rhythms index spontaneous cognitive operations during conscious rest, and that activity in these networks is associated with distinct EEG signatures.
EEG Alpha Power Modulation of fMRI Resting-State Connectivity
The results show that power fluctuations in posterior alpha oscillations result in local and long-range neural connectivity changes, and illustrate an enhanced functional inhibition during a higher alpha activity.

Topographic Electrophysiological Signatures of fMRI Resting State Networks
The data supports the physiological and neuronal origin of the RSNs and substantiates the assumption that the standard EEG frequency bands and their topographies can be seen as electrophysiological signatures of underlying distributed neuronal networks.
Electrophysiological correlates of the BOLD signal for EEG‐informed fMRI
The advantages of, and need for, simultaneous intracranial EEG–fMRI studies in humans, which recently became available and hold great potential to improve the understanding of the electrophysiological correlates of BOLD fluctuations.
