Scans Show 'Brain Dictionary' Groups Words By Meaning - 2 views

Lara Cowell on 27 Apr 16Scientists say they have made an atlas of where words' meanings are located in the brain. The map shows that words are represented in different regions throughout the brain's outer layer. Moreover, the brains of different people map language in the same way: words with related meanings lit up similar parts of the brain. Words meanings could pop up in different places simultaneously. Hearing the word "top" caused regions associated with clothing and appearances to light up. But "top" could also stimulate a region associated with words related to numbers and measurements. UC Berkeley neuroscientist, Jack Gallant, who authored the study, says the findings contradict two beliefs nonscientists commonly have about the brain. First, that only the left hemisphere handles language. Second, that the brain has localized regions which handle specific tasks. Contrary to those ideas, he says, language and meaning are distributed. "It's not that there's one brain area and one function," he says. But for Gallant, the real surprise is that the meanings of words triggered the same brain regions across multiple people in his study.
