Fmri analysis methods
WebfMRI study, we create data sets in which activation foci are artificially added so that their intensity and spatial extent are known. We then apply various methods of data analysis … WebClustering functional magnetic resonance imaging (fMRI) time series has emerged in recent years as a possible alternative to parametric modeling approaches. Most of the work so far has been concerned with clustering raw time series.
