A small pilot study, so no firm conclusions can be drawn, but this is an interesting and novel use of video games to help schizophrenic patients to control their hallucinations without drugs. The technique actually has almost nothing to do with the video game itself, which simply provides a feedback mechanism: this is all about the game controller. The game requires patients to land a rocket ship through direct use of the the auditory cortex, the activity of which is scanned using an MRI machine (don't try this as home!). This is similar in principle to other brain-computer interfaces, which have been around for decades in one form or another. The idea behind it is that, by learning to use the auditory cortex for this new purpose, patients are effectively training themselves to subdue/override the signals causing voices in their heads.
