Since the discovery of a set of correlated regions that increase their activation when people are not engaged in an active experimental task, the role of the “default mode network,” particularly during natural behavior in the real world, has been highly debated. Here, we collected intracranial multi-electrode recordings in twenty humans for 3-12 days of continuous neural and video recordings while participants engaged in natural activities, including interacting with family, watching TV, sleeping, etc. We show the default mode network emerges as a central homeostatic-like attractor in the brain’s dynamics that active behavior departs from in predictable trajectories.
