New research into the language capabilities of the brain indicates that several regions are associated with formulating a sentence.
This could be key to future brain injury treatment and language rehabilitation, with University of Rochester researchers indicating that different parts are activated for separate grammar tasks.
Scientists compare it to using specific toolbox tools for different tasks.
Study co-author Aaron Newman said: "Obviously we're doing something different [from other animals], because we're able to learn language unlike any other species.
"But it's not because some little black box evolved specially in our brain that does only language and nothing else."
Earlier this month, researchers at the University of Gothenburg found that epileptic activity in the brain during childhood can effect language development.
The findings were based on a study involving children divided into three groups - the first with epilepsy, the second with language difficulties and the third with language problems and epilepsy.
