In a nutshell Simple 40-hertz light and sound stimulation can induce brain rhythms that reduce Alzheimer’s pathology and improve cognitive function without invasive procedures or pharmaceutical side ...

In the following example, the bandwidth is 86 Hz to 20 kHz, and the bandwidth resolution is 40 Hz. Each sample represents a 40 Hz section of the displayed 19,914 Hz band. See oscilloscope.

but the key is delivering stimulation at 40 Hz. They all see beneficial effects." A decade of discovery at MIT Starting with a paper in Nature in 2016, a collaboration led by Tsai has produced a ...
