Fmri parametric analysis

WebChapter 6 - The Analysis of fMRI Data 6.3 Statistical Analysis of the Data Many techniques have been proposed for statistically analysing fMRI data, and a variety of these are in general use. The aim of such analysis is to produce an image identifying the regions which show significant signal WebIn this chapter we will cover how to analyze task-related data by using a technique called Psychophysiological Interactions (PPI), which reveals whether the functional connectivity between two nodes depends on what task the subject is currently doing. Example of a PPI analysis, taken from Outhred et al. (2015).
