Mind reading won't be just an intuitive thing from now on, thanks to a computer model that can figure out what word you are thinking, just by scanning your brain.

This computer model, developed by a team led by Tom Mitchell of Carnegie Mellon University in Pittsburgh, Pennsylvania, may reveal the mechanism by which the brain processes words and language and could ultimately come up with a technique that can deduce people's thoughts.

First, the computers were 'trained' in order to identify brain patterns linked with 60 images, which represented a different noun, such as 'celery' or 'aeroplane,' reports Nature.

The researchers proceeded further with the assumption that the brain processes words in terms of how they relate to movement and sensory information. For example, words like 'hammer', triggers the movement-related areas of the brain. However, the word 'castle' initiates activity in those regions of the brain that process spatial information.

In addition, the researchers were aware of the fact that different nouns are usually associated with some verbs more than that with others. For example, the verb 'eat' seems to be related with 'celery' than with 'aeroplane'. Thus, they designed the model apparently for using these semantic links to work out how the brain would react to particular nouns and thus they had put in 25 such verbs into the model.

Later, they scanned the brains of 9 volunteers for determining the images of the nouns by using functional magnetic resonance imaging (fMRI). Then they trained the model by feeding the model with 58 of the 60 nouns. And for every noun, this model scanned through a trillion-word body of text to know if it was related to the 25 verbs, and how that related to the activation pattern.
