I don't know that much about it, but I would say neurofeedback's emphasis is more on getting you to recognize how to calm down from wherever you are, and concentrate more on how to make the calming response happen in your body when you don't have the machines telling you if you're doing it right or not. it's kind of like a lie detector, only you get to hear the results, and you are trying NOT to set off the lie detector but rather get a "good buzz", by thinking of whatever calms you, or by relaxing different muscle groups in succession. I don't believe they purposely try to rile you up - that would definitely make things harder.
