Task-related activity influences brain connectivity through a two-level pattern modulation both in attentive networks and in the default mode network. While strengthening the local homogeneity, task execution reduces regional synchronization. It produces correlation patterns with opposite large and small scale properties. Task-related activity influences also the amplitude of the low frequency fluctuations in the same networks. The transition from resting state to steady state task execution, and the way back, causes a persisting slow drift in this quantity.
