The brain makes a lot of waste. Now scientists think they know where it goes
Scientists reveal synchronized brain waves during sleep aid in waste removal, potentially benefiting Alzheimer's and other brain disorders. Research in Nature suggests insights for human brain health and treatment development.

Scientists have discovered new insights into the brain's waste removal system, suggesting that synchronized waves during sleep help push fluid carrying waste products from deep within the brain to its surface. This waste is then absorbed into the bloodstream and eventually removed from the body by the liver and kidneys. The research, published in the journal Nature, sheds light on how the brain clears out waste, including toxins associated with Alzheimer's disease. Understanding this process could lead to better treatments and prevention strategies for various brain disorders. The findings also hint at potential implications for conditions like Alzheimer's, Parkinson's, headaches, and depression, all of which may be linked to impaired waste removal in the brain. While the studies were conducted on mice, researchers believe the results could offer valuable insights for human brain health and the development of therapies to support the brain's natural waste-clearance system.

The stimulation induced brain waves in the animals that occurred at the same, slow frequency.
Tests showed that the waves increased the flow of clean cerebrospinal fluid into the brain and the flow of dirty fluid out of the brain. They also showed that the fluid was carrying amyloid, the substance that builds up in the brains of Alzheimer's patients."
Does this mean we might be able to use something like TMS instead of sleeping?
And could a failure or reduced functioning in this system explain those people "allergic" to electromagnetic radiation?
Even before getting to the end this had me thinking of binaural beats. Back in college there was a beat that I would use whenever I was super tired and had a lot to do, and it'd help me refresh via a quick 20m nap (sometimes the nap itself wasn't even needed; just to let my mind be taken by the beat for the duration). If it's the case that a part of the effect is to trigger a "deep clean" (I've wondered on and off what's really happening), then this just may become a way to reduce said disorders...
Is that what dreams are? Electrical waves and fluid knocking on our brain cells?

The hypothesis is that driving neurons in this way aids in the removal of waste in the brain. It would be nice if they are correct.
> The visceral hypothesis suggests that during sleep, the central nervous system, particularly the cerebral cortex, switches from analyzing exteroceptive information to analyzing signals arriving from interoceptors distributed throughout all the systems of the body
