We now have 'brain fingerprinting' – a way of assessing guilt in criminal cases by monitoring brain activity as suspects are asked about their crimes. Much harder to fool than a standard lie detector, which requires people to be stressed by lying, this new technique uses the involuntary electrical signal in the brain known as a P300 wave.
