Mapping Language In The Brain

Scientists at the University of California, Berkeley, have built a "semantic atlas" that shows in vivid colours and multiple dimensions how the human brain organizes language. The atlas identifies brain areas that respond to words that have similar meanings. They show that at least one-third of the brain's cerebral cortex, including areas dedicated to high-level cognition, is involved in language processing. Notably, the study found that different people share similar language maps.

Detailed maps showing how the brain organizes different words by their meanings could eventually help give voice to those who cannot speak, such as victims of stroke or brain damage, or motor neuron diseases such as ALS.

Green words are mostly visual and tactile, red words are mostly social. Illustration: Copyright Alexander Huth / The Regents of the University of California
