neurofeedback toys

So there's this Kurzweil vaporware from 1998 (I guess NeuroSonics is just a holding company for a patent):

Brain Generated Music:

The user attaches three disposal leads to her head. A personal computer then monitors the user's brain waves to determine her unique alpha wavelength. [...] Music is then generated by the computer, according to an algorithm that transforms the user's own brain-wave signal. [...] the fact that the sounds are synchronized to the user's own alpha wavelength to create a resonance with the user's own alpha rhythm also encourages alpha production.

The music itself feels like it is being generated from inside your mind. Interestingly, if you listen to a tape recording of your own brain-generated music when you are not hooked up to the computer, you do not experience the same sense of transcendence. Although the recorded BGM is based on your personal alpha wavelength, the recorded music was synchronized to the brain waves that were produced by your brain when the music was first generated, not to the brain waves that are produced while listening to the recording. You need to listen to "live" BGM to achieve the resonance effect.

And now there's this brand new vaporware:
Project Epoc is a headset that uses a set of sensors to tune into electric signals naturally produced by the brain to detect player thoughts, feelings and expression. It connects wirelessly with all game platforms from consoles to PCs. Project Epoc now makes it possible for games to be controlled and influenced by the player's mind.

Are any of these electrical drugs actually on the market? Or does the fact that people have been playing with this stuff since the 70s and there are still no products more sophisticated than X-Ray Specs mean it has about the same mental effect as watching screen savers with your nose on the glass?

Still waiting for that Brainstorm / Strange Days tech... (Previously.)
