WebParametric analyses, in contrast, detected most true findings while generating relatively few false positives: on average, less than one of those very large clusters would be deemed a true finding in each brain-wide analysis. WebTo prepare the data for a parametric modulation analysis, we will create a preprocessing pipeline similar to the one we used for the example dataset here. If you haven’t already, go through the tutorial with the Flanker dataset; there you can find the details of each preprocessing and statistical analysis step, which we won’t discuss here in depth.

WebOct 6, 2006 · Critically, Statistical Parametric Mapping provides a widely accepted conceptual framework which allows treatment of all these different modalities. This rests on an understanding of the brain's functional anatomy and the way that measured signals are caused experimentally. WebFeature-space clustering for fMRI meta-analysis Clustering 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. In this contribution we investigate the applicability of a clusteri …
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).
