Criticality: The Brain’s ‘Sweet Spot’ for Learning and Preventing Decline

Link: ScienceDaily – The brain’s sweet spot: criticality

What the Study Did: Researchers from the University of Michigan used computational modeling to study “criticality,” a state between order and chaos in neural activity. They analyzed how criticality affects memory, learning, and flexibility in both healthy and Alzheimer’s-affected brains.

Summary: Optimal brain performance requires balance—not too rigid, not too chaotic. Sleep helps restore this critical state.

Why It Matters: Understanding brain dynamics may guide new treatment strategies and neuropsych assessments.

Patient Takeaway: Maintaining cognitive balance may involve sleep, stress management, and therapies that support brain flexibility.
