From the BBC:
Scientists say they have been able to monitor people’s thoughts via scans of their brains.
Teams at University College London and University of California in LA could tell what images people were looking at or what sounds they were listening to.
The US team say their study proves brain scans do relate to brain cell electrical activity.
The UK team say such research might help paralysed people communicate, using a “thought-reading” computer.
