Science decodes ‘internal voices’
Jason Palmer, BBC News:
[T]he team employed a computer model that helped map out which parts of the brain were firing at what rate, when different frequencies of sound were played.
With the help of that model, when patients were presented with words to think about, the team was able to guess which word the participants had chosen.
They were even able to reconstruct some of the words, turning the brain waves they saw back into sound on the basis of what the computer model suggested those waves meant.
Imagine a computer controlled with technology like this.
