We show the detection of whole-brain mouse Quasi-periodic patterns (QPPs), highlighting their interaction with the global signal and coincidence with anti-correlation between speculative mouse Default Mode (DMN) and Task-Positive (TPN)-like networks. We further investigated how QPPs interact with sensory information processing. By tracking QPP behavior during an fMRI visual stimulation block design, we illustrate how QPPs can become modulated by visual stimulation, triggering or diminishing their occurrence. We then linearly regressed QPPs from the fMRI images to show how QPPs underlie a substantial fraction of visual response magnitude and variance. These results suggest the relevance of QPPs in sensory processing.
