Story summary

Researchers at Washington University in St. Louis have unveiled a groundbreaking theory linking brain function to a delicate balance of order and chaos, known as "criticality." They found that disruptions, especially from tau protein accumulation in Alzheimer’s, hinder cognitive abilities. Remarkably, sleep can restore this balance, opening doors to innovative therapies and earlier diagnoses using fMRI technology.
