Fmri sliding window criticism
WebIn conventional resting-state functional MRI (R-fMRI) analysis, functional connectivity is assumed to be temporally stationary, overlooking neural activities or interactions that may happen ... Specifically, a sliding window approach is firstly employed to generate a sequence of overlapping R-fMRI sub-series. Based on these sub-series, sliding ... Webaddition, fMRI provides a good balance between spatial resolution the most common approach to assess rs‐dFC is by far the sliding for localization of activations in the brain as well as continuously window approach, whereby the fMRI data are segmented in (pos‐ increasing temporal resolution, as compared to magnetoencepha‐ sibly ...
