Novel data-driven analysis methods for real-time fMRI and simultaneous EEG-fMRI neuroimaging
… novel methods to perform data fusion between EEG and fMRI data acquired simultaneously. The core of this thesis is organized around four "experiments", each one addressing one of these specic aims. The main results can be summarized as follows. Experiment 1: a data analysis software has been …

Delineating the Neural Correlates of Visual Awareness through the Integration of Multimodal Neuroimaging and Noninvasive Electrical Neuromodulation
… neuromodulation. To this extent, we utilized simultaneous EEG-fMRI imaging to investigate both the electrophysiological and hemodynamic correlates of visual awareness during binocular rivalry. Binocular rivalry is a classic visual phenomenon in which one’s perception spontaneously fluctuates …

Identifying the Seizure Onset Zone using Intracranial EEG-fMRI
Simultaneous EEG-fMRI has been an effective technique for identification of the seizure onset zone (SOZ) in patients with refractory epilepsy. Recent studies have shown that using intracranial electrodes (iEEG) combined with fMRI offers unique insight into changes in blood oxygen-level dependent …

Safety and data quality of EEG recorded simultaneously with multi-band fMRI
Simultaneously recorded electroencephalography and functional magnetic resonance imaging (EEG-fMRI) is highly informative yet technically challenging. Until recently, there has been little information about EEG data quality and safety when used with newer multi-band (MB) fMRI sequences. Here, we …

Spatiotemporal brain imaging
… of functional magnetic resonance imaging (fMRI) with electroencephalography (EEG) and magnetoencephalography (MEG). fMRI provides millimeter spatial resolution, while EEG and MEG provide millisecond temporal resolution. The thesis is divided into two broad sections: Monte Carlo modeling …

Algorithms for enhanced spatiotemporal imaging of human brain function
… resolution. The electroencephalogram (EEG) and magnetoencephalogram (MEG) measure neuronal activity with high temporal resolution, and provide clinically accessible signatures of brain states. However, they have limited spatial resolution for regional dynamics. Combinations of M/EEG …
