Hi. I want to be more alert and realize more of surroundings. Which brainwave is needed for this and are there apps for that purpose? What I mean is such a thing like ADHD treatment via EEG. You know they treat ADHD by EEG. I want to be able to control my brainwaves. In normal EEG devices there are games you control something with brainwaves. Are there possibilities as such in Muse Calm? I will purchase Muse but I have reservations. I will not use it for Meditation.
