In Task based fMRI, the detectable activation is expected to diminish as the task continues over one minute. In this study, a comparison was made between a scan of the subject at rest and a scan of the same subject performing a task for the entire duration. The calculated functional maps were generated from multiple sections of the time series data in a sliding window manner. A consistent differentiation was observed in the independent components and seed-based functional maps between the resting scans and the scans under extended period of stimulation.
