Semantic atlas opens door to decoding what you want to say

Posted by April 27, 2016 | News | No Comments

In their paper in Nature, Frederic TheunissenJack Gallant and co-authors describe a data-driven approach to map language representation across the human cortex. Using fMRI to monitor brain activity during language processing, they were able to identify regions of the cortex that specifically respond to a set of related words, such as words representing numeric concepts, or emotional concepts. The resulting semantic map could eventually be used to decode what someone wants to say, giving a “voice to those who cannot speak, such as victims of stroke or brain damage, or motor neuron diseases such as ALS.” Read the full story in Berkeley News and the research article in Nature.
