Working Memory Revived in Older Adults by Synchronizing Rhythmic Brain Circuits
22nd June 2019
We developed a noninvasive stimulation procedure for modulating long-range theta interactions in adults aged 60–76 years. After 25?min of stimulation, frequency-tuned to individual brain network dynamics, we observed a preferential increase in neural synchronization patterns and the return of sender–receiver relationships of information flow within and between frontotemporal regions. The end result was rapid improvement in working-memory performance that outlasted a 50?min post-stimulation period.
