Concurrent EEG and Functional MRI Recording and Integration Analysis for Dynamic Cortical Activity Imaging Thinh Nguyen*1, Thomas Potter*1, Christof Karmonik2, Robert Grossman2, Yingchun Zhang1,3 1Department of Biomedical Engineering, Cullen College of Engineering, University of Houston, 2Department of Neurosurgery, Houston Methodist Hospital and Research Institute, 3Guangdong Provincial Work Injury Rehabilitation Center An EEG-fMRI multimodal imaging method, known as the spatiotemporal fMRI-constrained EEG source imaging method, is described here. The presented method employs conditionally-active fMRI sub-maps, or priors, to guide EEG source localization in a manner that improves spatial specificity and limits erroneous results.
