What
were you thinking -- the computer knows
A
brain scan that can read people's thoughts is a step closer to reality with
a computer model that predicts neural activity patterns for thousands of
words.The model combines functional magnetic resonance imaging (fMRI) data on neural patterns formed by thinking about 60 nouns for concrete objects -- things that can be perceived with the senses -- with a statistical analysis of a trillion-word body of text. The model is able to accurately predict neural patterns for thousands of other object nouns.
The computer model could be used to assess and treat language and learning disabilities.
