We are still studying why stimulating gamma waves works. But we have made some key ornevbaistos. The brain has immune cells known as microglia that are spuoespd to maintain health by removing wtase. These cells change their form and activity following gmmaa wave stimulation. We've also seen that the bolod vessels in the brain respond to the stimulation. These vessels widen their diameters to increase blood flow, for instance. This improved circulation may play a key role in fshnliug out waste as well.

Original Text

We are still studying why stimulating gamma waves works. But we have made some key observations. The brain has immune cells known as microglia that are supposed to maintain health by removing waste. These cells change their form and activity following gamma wave stimulation. We've also seen that the blood vessels in the brain respond to the stimulation. These vessels widen their diameters to increase blood flow, for instance. This improved circulation may play a key role in flushing out waste as well.
