Scientists move a step closer to mind-reading
Scientists have developed a method for reading a person's mind using brain scans.
Once it has been trained on an individual subject's thoughts, the computer model can analyse new brain scan images and work out which noun a person is thinking about - even with words that the model has never encountered before.
The model is based on the way nouns are associated in the brain with verbs such as see, hear, listen and taste. The research will inevitably raise fears that scientists could soon be able to read a person's mind without them realising.

Research team's work with brain scans and computational modeling an important breakthrough in understanding the brain and developing new computational tools
Predicted fMRI images for "celery" and "airplane" show significant similarities with the observed images for each word. Red indicates areas of high activity, blue indicates low activity.

How Technology May Soon "Read" Your Mind
The technology that is transforming what once was science fiction into just plain science is a specialized use of MRI scanning called "functional MRI," fMRI for short. It makes it possible to see what's going on inside the brain while people are thinking.
"You know, every time I walk into that scanner room and I see the person's brain appear on the screen, when I see those patterns, it is just incredible, unthinkable," neuroscientist Marcel Just told Stahl.
He calls it "thought identification."

Predicts Brain Activation Patterns for Thousands of Concrete Nouns
The team, led by computer scientist Tom M. Mitchell and cognitive neuroscientist Marcel Just, constructed the computational model by using fMRI activation patterns for 60 concrete nouns and by statistically analyzing a set of texts totaling more than a trillion words, called a text corpus. The computer model combines this information about how words are used in text to predict the activation patterns for thousands of concrete nouns contained in the text corpus with accuracies significantly greater than chance.
