Tuning in to the Rhythms of Aging Brains

Published on September 12, 2022

Just like a well-orchestrated concert, our brain functions rely on rhythmic neural activities. However, as we age, these activities can become out of sync and chaotic. But fear not! Scientists believe that by using non-invasive rhythmic brain stimulation, we can restore the natural frequencies of neural activities in aging brains to match those of younger, healthier brains. It’s like bringing a misbehaving choir back in tune! This technique shows promise not only for those experiencing aging-related cognitive decline but also for individuals with neurodegenerative diseases and neuropsychiatric disorders. While there is still much research to be done in this exciting field, the potential benefits for restoring normal brain functions are immense. So grab a ticket to this scientific symphony and dive deeper into the research!

Rhythmic neural activities are critical to the efficiency of regulatory procedures in brain functions. However, brain functions usually decline in aging as accompanied by frequency shift and temporal dedifferentiation of neural activities. Considering the strong oscillations and long-lasting after-effects induced by rhythmic brain stimulations, we suggest that non-invasive rhythmic brain stimulation technique may help restore the natural frequencies of neural activities in aging to that in younger and healthy brains. Although with tremendous work to do, this technique offers great opportunities for the restoration of normal brain functions in aging, or even in those suffering from neurodegenerative diseases and neuropsychiatric disorders.
