No, this isn’t about psychics, but about major advances in technology that use brain waves to tell if a person is lying or not.

Richard Jones is the director of the Christchurch Neurotechnology Research programme at the New Zealand Brain Research Institute, and a senior biomedical engineer and neuroscientist in the Department of Medical Physics and Bioengineering of Canterbury District Health Board.

He tells us about a project he’s been involved with at the Canterbury University school of law, which he describes as a “knowledge detector”. It’s a variation of an EEG, and it detects brain waves which indicate whether the person being tested knows about certain things.
