Remote Detection of Brain Activity

Nita Farahany (Law, Vanderbilt) has written a very interesting article on remote detection of brain activity in the Washington Post.  Here's a sample:

Police may soon be able to monitor suspicious brain activity from a distance as well. New neurotechnology soon may be able to detect a person who is particularly nervous, in possession of guilty knowledge or, in the more distant future, to detect a person thinking, "Only one hour until the bomb explodes." Today, the science of detecting and decoding brain activity is in its infancy. But various government agencies are funding the development of technology to detect brain activity remotely and are hoping to eventually decode what someone is thinking. Scientists, however, wildly disagree about the accuracy of brain imaging technology, what brain activity may mean and especially whether brain activity can be detected from afar.

Yet as the experts argue about the scientific limitations of remote brain detection, this chilling science fiction may already be a reality. In 2002, the Electronic Privacy Information Center reported that NASA was developing brain monitoring devices for airports and was seeking to use noninvasive sensors in passenger gates to collect the electronic signals emitted by passengers' brains. Scientists scoffed at the reports, arguing that to do what NASA was proposing required that an electroencephalogram (EEG) be physically attached to the scalp.

But that same year, scientists at the University of Sussex in England adapted the same technology they had been using to detect heart rates at distances of up to 1 meter, or a little more than three feet, to remotely detect changes in the brain. And while scientific limitations to remote EEG detection still exist, clearly the question is when, not if, these issues will be resolved.

The Onion, a US parody new website, gives its own off-color take on these sorts of issues here:
