The human brain requires rest states independent of sleep
Neuroimaging research consistently shows that the human brain engages in active, highly organized intrinsic states—such as those mediated by the default mode network—during wakeful rest, demonstrating that the brain requires functional rest states independent of sleep.
The retrieved papers provide strong neuroimaging and physiological evidence showing that the human brain maintains distinct, active resting states (such as the default mode network) during wakeful rest, which are critical for cognitive function, memory consolidation, and baseline regulation independent of sleep. None of the papers refute the claim.

The paper demonstrates that the default mode network activates significantly during brief resting states, indicating distinct functional processes during wakeful rest independent of external tasks.

The study identifies intrinsic resting-state networks like the DMN as functional baselines of the brain during relaxed non-task states.

The research highlights that neural activities such as rhythm regulation and memory replay occur during the brain's resting states, supporting cognitive functions outside of sleep.
