Brain scans have been developed which it is claimed can predict what a person is about to do.
German, British and Japanese scientists were able to “read minds” using sophisticated functional magnetic imaging (fMRI) and computer programs.
Current Biology reported people were asked to think about adding or subtracting – scientists were able to read intentions in 70% of cases.
The researchers, led by scientists from the Max Planck Institute for Human Cognitive and Brain Sciences, in Leipzig, asked people to hold their mathematical decision in their minds until they were shown two numbers on a computer screen.
The fMRI scans monitored brain activity for the few seconds they were thinking about their sum, and it was on this information that the scientists made their predictions.
The researchers used a method called “multivariate pattern recognition”.
