Language localized in the brain

Functional specificity refers to the idea that discrete parts of the brain handle distinct tasks. To determine this, the researchers analyzed each subject individually using fMRI, making sure thatpatterns of activity in one brain would only ever be compared to patterns of activity from that same brain.The researchers spent the first 10 to 15 minutes of each fMRI scan having their subject do a fairly sophisticated language task while tracking brain activity. This way, they established where the language areas lie in that individual subject, so that later, when the subject performed other cognitive tasks, they could compare those activation patterns to the ones elicited by language. The researchers said the results don t imply that every cognitive function has its own dedicated piece of cortex.
