Huh, wow. I was expecting this to be about deep-brain stimulation, but it looks like they used a non-invasive technique. And it sounds fascinating. It looks like they analyzed peoples' theta and gamma waves in different regions of their brain, and tried to 'nudge' them towards staying in sync. Theta/gamma/whatever waves are defined by the frequency at which the signal occurs, sort of like radio bands, and it sounds like this study presents the brain as a bunch of analog circuits which eventually develop stuff like noise and clock drift. >Here we show that a core feature of cognitive decline may emerge from the temporal decoupling of neural codes theorized to constitute a flexible frontotemporal circuit for the monitoring and storage of memory contents of real-world information. The work supports theories of neurocognitive aging that propose cortical disconnection underlies age related cognitive decline... Neat. Sounds like we need thicker wires.
