Using low-resolution electromagnetic tomography (LORETA) (Pascual-Marqui 2002, 2007) to estimate cortical EEG sources and independent components analysis (ICA) to identify synchronous source activity, he demonstrated EEG networks involving similar cortical regions to those identified by resting state fMRI
from the literature.
Some studies have used PET and fMRI
to study functional diseases of the gastrointestinal tract and visceral sensation hypersensitivity.
The results showed that these countermeasures lowered the accuracy of the test by about 20 per cent because it was more difficult for fMRI
to find any differences in brain activity.
Resting state fMRI
: A review on methods in resting state connectivity analysis and resting state networks.
To make early diagnosis and to accurately identify the dysfunctional or effected regions of brain PET, SPECT or fMRI
are mostly used.
The results of the simulated and real fMRI
data both demonstrated that semiSRC-AVE exhibited a more stable and better performance than the supervised SRC with an average coefficient (SRC-AVE) method.

Despite the widely developed approaches to analyze EEGfMRI data, there is still no method that focuses on two challenging issues of simultaneous EEG-fMRI fusion; one is to handle the mutual interference between EEG and fMRI
, and the other is to handle the nonlinearity of EEG-fMRI data.
In this study, we explored neural plasticity in BP patients using task-related and resting-state fMRI
. We found that the early stage of BP is associated with significant decreases in ReHo, fALFF and ICC values in the contralateral S1/M1, and with significant decreases in ReHo and ICC values in the ipsilateral S1/M1, compared to matched healthy controls.
More recently, with the advantage of imaging resolution, blood oxygen level-dependent (BOLD) contrast in functional magnetic resonance imaging (fMRI
) has been often used for CVR assessment (13-18).
