Functional Magnetic Resonance Imaging (fMRI) is a class of imaging methods developed in order to demonstrate regional, time-varying changes in brain metabolism 3, 37, 49. These metabolic changes can be consequent to task-induced cognitive state changes or the result of unregulated processes in the resting brain.

In case of fMRI files, the fourth dimension (almost) always represents the “time” dimension. So you can assume that a nifti image of an fMRI file has 4 dimensions, with the first three being the spatial dimensions (similar to the anatomical MRI file: \(X \times Y \times Z\)) and the last (fourth) being the time dimension (\(T\)). So for the above file, you can assume …fMRI analysis workflow. The general steps involved in this fMRI analysis pipeline are summarized in the following chart: Analyzing the anatomical data involves taking the T1 anatomical scan and feeding it to the FreeSurfer algorithm. This will result in both “cleaned” T1 volume images and cortical surface objects.In this animation, two different smoothing kernels (4mm and 10mm) are applied to an fMRI scan. Notice that as we use larger smoothing kernels, the images become blurrier and the anatomical details become less distinct. Also note that, for the sake of simplicity, this animation uses a 2D slice of the brain to demonstrate this preprocessing step.On the first day, the subjects had their brains scanned in an fMRI machine while seeing photos of 200 novel faces, with instructions to try to remember the faces.
