I don’t know if it causes gamma waves but gamma is considered the default network signal of the brain meaning it’s main benefit is allowing multiple areas of the brain to exchange information with each other to a degree far more than usual. The tag has hemispheric connection enhancement, so at the very least you are seeing a big benefit that is comparable to what gamma can do.
The hemispheric connection was the main reason I bought this tag. After 4 days, I finally had my first epiphany without even trying, much like what I was describing when I suggested people should listen to hemispheric connection with Focus.
I’ve also noticed that I’m unable or unwilling to entertain myself with things I used to like tv or video games. I’m literally only able to be entertained at this point by college lectures on behavioral biology and physics, and John Oliver. Lol.
