>exposed laboratory mice that genetically predisposed to Alzheimer's disease to a light flickering at 40 hertz for one hour a day. They found that this treatment reduced the levels of tau and amyloid beta in visual cortex of the brain and stimulated the activity of debris-clearing immune cells.

does it mean that old CRT TVs and monitors kept our Alzheimer at bay?

weren't fluorescent lights 40Hz?

I guess it depends how important the 40hz is. Because PAL was 50hz and NTSC was 60hz (if my addled memory is still working ok).

But it did occur to me that my years of going to raves, hearing (and feeling) sub-bass (in the 30-60hz range) could have a similar effect (especially when you throw in the strobe lights).

My old CRT monitor, an IBM 5154 clone, gave me a mild sunburn on the day I got it...

There was a RadioLab special on this a few years ago: https://www.wnyc.org/story/flashing-light-therapy-alzheimers...

After hearing this intriguing RadioLab episode some months back, I started searching around youtube for 40 Hz tones and found quite a lot of videos of all kinds that use those and other tones allegedly related to various brain waves (Alpha, Beta, Gamma, etc).

I listened to a whole bunch of these videos, and while I wasn't measuring my memory, I did pay close attention to how the sounds made me feel, and this one particular made me feel strangest: [1]. Unfortunately, the sound fades in and out and the effect goes with it. I wish it could have had stayed at a steady volume so that the effect could be sustained. If you watch it, just ignore the cheesy graphics and listen.

Here are some other interesting ones: [2], [3], [4], [5], [6]

Video [3] is actually supposedly 40 Hz.
