The complexity of raw functional magnetic resonance imaging (fMRI) data with artifacts leads to significant challenges in multioperations these data. FMRI analysis is extensively used neuroimaging fields, but the tools for processing fMRI are lacking. A novel APP DESIGNER conversion, preprocessing, and postprocessing (CPREPP fMRI) tool proposed developed this work. This toolbox intended pipeline analysis, including full data, starting from DICOM then checking quality at each step, ending...

Abstract Recent evidence suggests that the brain intrinsic activity during rest might be as significant task evoked activities and consumes considerable energy linked to neural signaling processes. We performed an fMRI study recently aiming compare differences in between patients with obsessive-compulsive disorder healthy volunteers a simple suppression paradigm. hypothesized would show default mode network (DMN) connectivity dissociations from individuals. OcD had higher (p < 0.05) than...
