I used a variety of neuro devices for measuring and monitoring purposes. In addition to for sleeping and meditating I also use other electroencephalography (EEG) devices for training my brain for focus.
I don't have focus problems despite being NT with ADHD. I have done enough work on my mind, environment, and knowing what I need for balance to be able to keep myself on track. However, the DATA is most valuable for long term analysis and knowing what works BEST for specific things.

EEGs are used to diagnose and evaluate a number of things like: seizures, sleep disorders, Alzheimer's, different kinds of brain injuries etc.
Understanding how your brain and body work both separately and together is a huge component in unlocking many of the things that plague emotional well being.
Don't be a stranger to yourself mentally, physically, or spiritually.
The more you know and understand about yourself, the better you will be in all things and the better you will be for others.
