Hello, I know there are a lots of methods/practice to train different kind of brainwaves.
if I want to train gamma brainwaves with eyes open, what activities/routines should I do?
How about beta, alpha, theta, and delta?
From what I know, meditation practice have significant impact of brainwaves for long term practice. But different kinds of meditations might result in different brainwaves.
Online resources/books are always welcome.
