Resting State-fMRI represents an emerging and powerful tool to explore brain functional connectivity (FC) changes associated with neurologic disorders. Compared to activation/task-related fMRI, Resting State fMRI has the advantages such as (i) Blood oxygen level dependent (BOLD) fMRI signals are self-generated and independent of subject's performance during the task and (ii) a single dataset is sufficient...
Electrogastrography (EGG) is an experimental non-invasive method that reflects the myoelectrical activity of the diabetic gastroparesis (D-GP) and healthy subjects gastric system. In clinical world, endoscopy and delayed gastric emptying diagnosis test are using for understand the D-GP patient's condition which are invasive, quite expensive and uncomfortable. Therefore our aim is to evaluate the Electrogastrography...
Bi-frequency Coherence is a normalized spectrum function based on Loève Spectrum. In this work, we investigated the use of Bi-frequency Coherence function for correlation of two non-stationary processes, particularly for EEG signals. We define a procedure to achieve Bi-frequency Coherence starting from Loève Spectrum. Then we present a numerical estimation of this approach. We compare our method with...
