Gamma-range activity is often discussed as part of how brain networks coordinate information. In Alzheimer’s disease, those networks can become disrupted early—years before symptoms become severe—so scientists have been curious: If we support timing and coordination of Gamma activity in the brain, could we end up influencing disease biology? What animal studies found (and why they got so much attention) The modern wave of 40-Hz Alzheimer’s research gained traction after a 201
