Simultaneous fMRI and EEG source localization with visual motion stimuli
Introduction Simultaneous acquisition of fMRI and EEG is thought to be a potential solution for enhancing the temporal resolution of fMRI. To enhance the temporal resolution of fMRI with aids of the EEG data, it is essential to match the fMRI data precisely with the EEG data in the spatial domain. For better spatial matching between fMRI and EEG, we applied EEG source localization to the EP/ERP...
متن کاملCorrelation of BOLD Signal with Linear and Nonlinear Patterns of EEG in Resting State EEG-Informed fMRI
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 nonline...
متن کاملCorrelation between BOLD-fMRI and EEG signal changes in response to visual stimulus frequency in humans.
The correlation between signals acquired using electroencephalography (EEG) and fMRI was investigated in humans during visual stimulation. Evoked potential EEG and BOLD fMRI data were acquired independently under similar conditions from eight subjects during stimulation by a checkerboard flashed at frequencies ranging from 2-12 Hz. The results indicate highly correlated changes in the strength ...
متن کاملTransfer Function between EEG and BOLD Signals of Epileptic Activity
Simultaneous electroencephalogram (EEG)-functional Magnetic Resonance Imaging (fMRI) recordings have seen growing application in the evaluation of epilepsy, namely in the characterization of brain networks related to epileptic activity. In EEG-correlated fMRI studies, epileptic events are usually described as boxcar signals based on the timing information retrieved from the EEG, and subsequentl...
متن کاملAn fMRI study of human visual cortex in response to spatiotemporal properties of visual stimuli
ABSTRACT Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF). Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd. Results: Average percentage BOLD signa...
