Brain scans now allow researchers to know exactly what a person is imagining.
The latest breakthrough comes after scientists used brain scans to decode images directly from the brain.
Researchers have been able to put together what numbers people have seen, the memory a person is recalling, and even reconstruct videos of what a person has watched.
‘We are trying to understand the physical mechanisms that allow us to have an inner world, and a part of that is how we represent other people in our mind,’ said Cornell University cognitive neuroscientist Nathan Spreng.
Spreng’s team gave 19 volunteers descriptions of four imaginary people.
