Ah, yes I am familiar with this. I've used a similar device during some biofeedback treatment. The leap with the imaging tech is that it is a 1:1 correlation. As far as I am aware the other tech still relies on mapping cues from the brain that aren't directly 1:1 For example, boosting your high beta waves moves your game character forwards, etc. With the imaging technology, you don't have to perform mental gymnastics, you just "picture" the image you are after and the like.
