fMRI Activation map and Subtraction

Activation maps — FMRIB Centre, University of Oxford
This Oxford webpage guides you through a simple fMRI experiment

To highlight a particular region's activation scientifically, a subtraction technique between a simulated and a control run of the experiment is frequently used. This minimises risk of misinterpreting activation from another area, a region that is not of significant interest to the experiment or study.
