Early-stage trials in Alzheimer's disease patients and studies in mouse models of the disease have suggested positive impacts on pathology and symptoms from exposure to light and sound presented at the gamma band frequency of 40 Hz.
A new study zeroes in on how 40Hz sensory stimulation helps to sustain an essential process in which the signal-sending branches of neurons, called axons, are wrapped in a fatty insulation called myelin. Often called the brain's "white matter," myelin protects axons and insures better electrical signal transmission in brain circuits.
Said Li-Huei Tsai,"This study shows that it's not just gray matter, but also white matter that's protected by this method."
This year Cognito Therapeutics published phase II human trial results indicating that 40Hz light and sound stimulation significantly slowed the loss of myelin in volunteers with Alzheimer's.
This year, Tsai's lab also published a study showing that gamma sensory stimulation helped mice withstand neurological effects of chemotherapy medicines.
In the new study, Amorim and Tsai's team found that 40Hz light and sound not only preserved myelination in the brains of cuprizone-exposed mice, it also appeared to protect oligodendrocytes (the cells that myelinate neural axons), sustain the electrical performance of neurons, and preserve a key marker of axon structural integrity. When the team looked into the molecular underpinnings of these benefits, they found clear signs of specific mechanisms including preservation of neural circuit connections called synapses; a reduction in a cause of oligodendrocyte death called "ferroptosis;" reduced inflammation; and an increase in the ability of microglia brain cells to clean up myelin damage so that new myelin could be restored.
The findings suggest that gamma sensory stimulation may help not only Alzheimer's disease patients, but also people battling other diseases involving myelin loss, such as multiple sclerosis, the authors wrote in the study.

It seems remarkable that something working on the eyes and ears can heal completely separate areas of the body, but it can.
“...may preserve brain’s ‘white matter’”
Surprised they were able to get it published.
Ty very much for posting these, especially the ones on alzheimers-
That’s why bass players are smarter.
Belay that.
Here’s a better one that is based on MIT’s actual 10,000 HZ wave that makes the exact 40HZ clicks.

Link to a different wavelength I think- not sure.

40 Hz light must be pretty bright. /s
Beyond annoying. Even just for a few seconds.
Are we sure this isn’t sort of like the jabs—intended to do in those they’d like to nudge off this mortal coil?
Beat me to it.
I have 8 or 9 40Hz generators at any given time. They put me through college and I teach others how to use ‘em.
Yeah, maybe. I got a headache after a few moments.
Strangely, it made me sleepy in just a couple minutes.
It is an annoying sound, but I also felt quite relaxed, and I had some coffee this morning.
I feel like a nap is needed.
“Strangely, it made me sleepy in just a couple minutes.”
Exactly the same thing happened to me. And actually put me to sleep at an early morning time it is ordinarily very difficult to get back to sleep.
It puts my parakeets to sleep!!! They can not keep their eyes open!
Also, fascinating to watch the “Exact 40 Hz Gamma Brainwave audio used by MIT to prevent Alzheimer’s” on a spectral analyzer, my favorite being Android “Spectroid” with traditional chart and waterfall presentations. And it seems to be one of the most directional sounds I have ever encountered, at least while playing on my phone. If it turn the phone off-axis in the slightest my perception of the sound volume drops considerably (but then I’m almost 70 and 10 khz is getting up there). But I’m sure the birds can hear it fine.
Also, the perceived volume has to be pretty high to make me sleepy. If the volume is only that of say a radio playing in the background it doesn’t. But if the phone is pointed right at my ear from a foot away or so it does.
Interestingly, another bird I have, a Conure, is curious about the sound but doesn’t seem to get sleepy.
It looks to me like the clicking goes all the way down to about 1.2 khz.
