Brain Scan Reads Your Mind

Source: BBC

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.

A UK expert advised caution, but said such technologies would develop.

Such techniques could be used to help people who are paralysed - there are already some steps being taken towards helping people using computer-assisted prosthetic devices linked to computers.

But this research might also allow abstract thoughts and intentions to be read.

It may even be possible to carry out instructions such as "send email" simply by thinking them - with a scanner picking up the wish and translating it in a way that the computer can act on.
