You’ve probably heard of biofeedback – where real-time feedback on bodily processes that were previously considered to be automatic. Biofeedback is typically used to monitor stress and muscle tension.

Neurofeedback – real-time feedback on the state of the brain – has been experimented with since the 1960’s, and experimenters have developed the technology to the point where it may be used to control video games as a recent Wired article describes. This technology is already used by paraplegics to control their wheelchairs, open doors, etc. Medical researchers are worried that controlling a game with your mind may train the brain in ways that may not be optimal for it’s function, and could have a negative psychological impact. It certainly sounds a lot safer than the project which Kevin Warwick had planned several years ago of implanting an electrode in his brain, and one in another person’s brain to see if they could communicate. (He asked his wife initially, but she wasn’t keen 🙂 )

This seems to me to have some really interesting implications. Could we train ourselves through neurofeedback to be more satisfied with our life? Would this be beneficial anyway? According to wikipedia, this technology is being used therapeutically in the treatment of psychological conditions such as addiction.
