<P> Language processing has been linked to Broca 's area since Pierre Paul Broca reported impairments in two patients . They had lost the ability to speak after injury to the posterior inferior frontal gyrus of the brain . Since then , the approximate region he identified has become known as Broca 's area , and the deficit in language production as Broca 's aphasia , also called expressive aphasia . Broca 's area is now typically defined in terms of the pars opercularis and pars triangularis of the inferior frontal gyrus , represented in Brodmann 's cytoarchitectonic map as areas 44 and 45 of the dominant hemisphere . Studies of chronic aphasia have implicated an essential role of Broca 's area in various speech and language functions . Further , fMRI studies have also identified activation patterns in Broca 's area associated with various language tasks . However , slow destruction of the Broca 's area by brain tumors can leave speech relatively intact , suggesting its functions can shift to nearby areas in the brain . </P>
