New research proposes a unified theory of brain function based on criticality—a state where the brain teeters between order and chaos, allowing it to learn, adapt, and process information optimally. When the brain strays from this delicate balance, cognitive performance weakens, and neurological disorders such as Alzheimer’s may begin to take hold.
