Simultaneous EEG and fMRI: towards the characterization of structure and dynamics of brain networks

Christoph Mulert
2013 Dialogues in Clinical Neuroscience  
Both methods are very sensitive to changes of synaptic activity, suggesting that with simultaneous EEG and fMRI the same neural events can be characterized with both high temporal and spatial resolution  ...  The specific appeal of the combination is related to the fact that both methods are complementary in terms of basic aspects: EEG is a direct measurement of neural mass activity and provides high temporal  ...  Another issue in simultaneous EEG-fMRI is the quality of the EEG recorded in the scanner.  ...

Acknowledgments This work was supported by the Engineering and Physical Science Research Council (EPSRC) for funding this research (APB EP/F023057/1, EP/J002909/1.  ...  Modelling fluctuations in RVT and HRI with the GLM allows us to account for BOLD signal variability that is unrelated to neuronal activity, and removing these potential confounds will improve our estimate  ...  Finally, using an additional recording of EEG-fMRI responses to visual stimulation we investigate how the spatiotemporal pattern of dynamic alpha-BOLD correlations relates to the magnitude of the brain's  ...
