10. Maintaining Consciousness
Continuous background activity in the brain is essential for maintaining consciousness and basic awareness. Even when we aren’t actively engaged in any particular task, networks like the DMN help keep us alert to our surroundings and internal states. This persistent activity forms the foundation for our sense of presence and ability to respond to new stimuli. Without it, the very fabric of our conscious experience—our thoughts, feelings, and perceptions—would unravel, leaving us in a state of unawareness.
