Once you are hooked up you are expected look at a screen and listen to some music(usually classical), and try to get your frequency responses below some baseline. Basically strengthening them like a muscle. You actually train yourself based on the feedback the sensors are giving you.
I managed to do some reverse engineering and figure out how the brain works to blow the numbers out of the water. Going from far below average to way above in a matter of months changed my life. I even figured out some things the center never tried before. Like significantly increasing the time I try to maintain the baseline, which allowed me get above average results. There was a lot more I figured out, but far to much for a HN post. Feel free to email for more info. I might make a post on it one day.
I also thought about doing this at home, but the risks are just too great to mess with something as deep as the Sensory-Motor function. I was happy to work with trained experts who monitor and correct problems. There is actually a lot to it, but the treatment is only a few months and you never really need think about it ever again. Since you can focus on doing things instead of endlessly trying improving brain function.
The website wasn't super clear on what Neurofeedback was after a cursory glance. Here's the summary from wikipedia[1] for anyone that is curious.
> Neurofeedback (NFB), also called neurotherapy or neurobiofeedback, is a type of biofeedback that uses real-time displays of brain activity—most commonly electroencephalography (EEG)—in an attempt to teach self-regulation of brain function. Typically, sensors are placed on the scalp to measure electrical activity, with measurements displayed using video displays or sound.
