Where does Chomsky claim this? As far as I know, he has never claimed any particular part of the brain is responsible for language. The claim of Chomsky's UG is that there is a genetic component to the language faculty of humans. That's pretty much a truism given that we can speak and our closest biological relatives can't. Presumably this cashes out somewhere in our brain. There's evidence that certain regions of the brain are involved in Language (Broca & Wernicke's areas) given evidence from brain injuries and their effect on language. He does posit an LAD (language acquisition device) but this is a logical/theoretical construct, to aid in theory building. It seems very likely that we have this given the universality of language in our species and our ability to learn the language of our own culture. The LAD though has not been claimed to be physically located somewhere in our brains by Chomsky (again afaik). Though presumably if we have it, it is fairly likely to be somewhere within our skulls.
