Acquisition of electroencephalogram (EEG) during functional magnetic resonance imaging (fMRI) provides an additional monitoring tool for the analysis of brain state fluctuations. The exploration of brain responses following inputs or in the context of state changes is crucial for a better understanding ...
The exploratory analyses reveal significant changes in hemispheric lateralities of upper alpha and high-beta current source densities in the prefrontal regions, consistent with upregulation of the FAA and FBA during the rtfMRI-EEG-nf task. Similar laterality changes are observed for current source ...
SIMULTANEOUS EEG-FMRI IN PATIENTS WITH ALZHEIMER'S DISEASE: ARE BOLD SIGNAL FLUCTUATIONS IN THE DEFAULT MODE NETWORK CORRELATED WITH ALPHA BAND POWER? desynchronization and synchronization (ERD/ERS) of α (about 10 Hz) and β (about 20 Hz) rhythms in association with the execution (with visual...
P19-12 The reticular activating system is associated with spontaneous fluctuations of alpha rhythm: a simultaneous EEG/fMRI studyRecently, modular organization of intrinsic brain networks has been revealed by the graph theoretical analysis of resting-state functional MRI (rs-fMRI). In this paper, we...
After collecting simultaneous resting-state EEG-functional magnetic resonance imaging data, the effect of rhythm modulations on FC was explored using what we term "dynamic rhythm information." We also investigated the synergistic relationships among three networks under rhythm modulation conditions, where ...
Real-time fMRI neurofeedback (rtfMRI-nf) with simultaneous EEG recordings is a promising neuromodulation approach that allows volitional regulation of blood-oxygenation-level-dependent (BOLD) activity of a target brain region and investigation of related electrophysiological activity. We discuss application...
Here, we test our proposed interpretation that this network underpins maintenance of tonic alertness. We used simultaneous acquisition of functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) in the absence of any paradigm to test an ensuing hypothesis, namely that spontaneous ...
