Components of fMRI
The following images highlight various protocols showing different aspects of the fMRI acquisition tasks. High resolution anatomical images are required in order to 'map' functional data sets onto them. Since the surgeon can see only anatomy, the anatomy provides the common reference points for functional location.

Areas
of the brain which yield higher signal intensity indicate the presence
of higher amounts of oxygenated blood.By timing the cognitive task that
the patient performs with the image acquisition sequence, the higher signal
intensity in these areas is related to the cognitive task.
