This is pure Philip K. Dick: in June a judge in India found a woman guilty of murdering her former fiancé and sentenced her to life in prison. The smoking gun? Test results obtained using the Brain Electrical Oscillations Signature test (BEOS) developed by Indian neuroscientist Champadi Raman Mukundan. The BEOS software uses an EEG to determine whether the subject is recalling specific details of a crime as they are being read aloud. BEOS "works" because as the crime's details are recited to a subject, their brain lights up in specific regions -- the areas that (in theory) show measurable changes when experiences are relived. According to Mukundan, the system can distinguish between peoples' memories of events they witnessed and deeds they committed. Gee, now that we have the technology to read criminal's minds and predict crimes we'll be expecting a crime-free society any minute now.

Frighteningly enough, this isn't the first (or second) time that we've seen scientists pat themselves on the back for creating a mind-reading machine, but a dedicated team from Carnegie Mellon has just announced a computer that "has been trained to read people's minds by looking at scans of their brains as they thought about specific words." In a completely unsurprising move, gurus familiar with the development are suggesting that the breakthrough could be used to better understand how the brain organizes knowledge, and eventually, treat language disorders and learning disabilities more effectively. That's all gravy from here, but when this stuff starts passing as evidence in court, you'll know it's time to seriously investigate a relocation to Mars.

What were we talking about again? Oh, that's right. Brains. Wonderful, delicious... brains. A new study published in the Proceedings of the National Academy of Sciences shows that researchers can track grey matter for the patterns that precede careless errors. Apparently there's a detectable activity shift when your brain switches to auto pilot -- which can happen as much as half a minute before you screw up. The hope behind the research is to be able to track brain activity and alert users who are headed off the tracks. The technology could reduce work slip-ups, improve driving, or at least help you know when to take a nap or switch activities to keep engaged. But seriously, what were we just talking about?

Minority Report has proven itself to be a fairly prescient movie on more than one occasion and, as this latest development shows, it seems that researchers haven't mined those Dickian ideas dry just yet. While we've already seen some software that supposedly helped to predict future crimes, The Guardian is now reporting that a team of neuroscientists have brought pre-crime technology to a new, even creepier level, developing a brain scan that can purportedly read people's intentions before they act on them. It's apparently still a ways off from going into service, however, with tests of the technology currently centered around predicting a subject's response to a simple math question. Nonetheless, the researchers seem to be well aware of the technology's potentially more complex uses, and are calling for an ethical debate over its possible use in interrogation. On the flipside, they also see the technology eventually being used in some less ethically-challenging applications, such as helping people control artificial limbs or operate a computer simply by thinking about it.

Seems kind of old school if your brain interface doesn't provide extra-sensory enhancement or integration to robotic limbs, but researchers at Carleton University in Ottawa, Canada are working on a system for thought-based biometrics by scanning and interpreting each individual's unique brain-wave signatures that occur when they think of a certain thought or can identify patterns uniquely -- kind of like that Peter Pan pixie dust thing, except in this case you get granted access to your box. For a variety of reasons the system isn't without its doubts and detractors, and will probably continue to have them so long as you have to wear an EEG cap on your scalp to get a reading -- though according to UCLA professor and BCI expert Jacques Vidal, rocking that headgear's the least of this system's problems. But if you expect us to shrug off any system that lets us interface with our gear via mind-link, you're sorely mistaken. So keep at it Carleton U, let's see some thought scanners.
