Of course the whole brain is used in language. The human brain, the most complicated structure in the known universe, evolved. Had it been designed, we might find nice separate compartments for language, motion, thought and so on. But evolution is utterly opportunistic. Any genetic mutation that increased our capacity for language, even a little bit, had a chance to be adopted, no matter where it took effect (23 September, p 6).
