For decades, neuroscientists have known that specific regions in the brain's left hemisphere are responsible for processing language. However, a new study by MIT researchers shows that language processing also occurs in many other parts of the brain. Using functional magnetic resonance imaging (fMRI) data from more than 700 people, the researchers identified 17 additional regions of the brain that appear to play a role in language. These regions are scattered across the brain, including parts of the cerebellum, hippocampus, and cerebral cortex, and they make up about 5 percent of the total volume of the adult brain ' about the size of a large strawberry. 'Even though there are all these distant components, it's pretty restricted in terms of volume. You don't need that much of the brain to do language,' says Evelina Fedorenko, an MIT associate professor of brain and cognitive sciences, a member of MIT's McGovern Institute for Brain Research,and the senior author of the study.
