In this review, we (i) describe the nomenclature of Broca's area and show how the circumscribed definition of Broca's area is disassociated from Broca's aphasia, (ii) describe in detail how the gross anatomy of Broca's area varies between people, and how the definitions vary between studies, (iii) attempt to reconcile the findings of structural…

Recent methodological advances prompted numerous neuroactivation studies on the anatomical localization of language functions. As a principal reference, the term "Broca's area" was anatomically connected to the inferior frontal gyrus and functionally related to expressive speech function. The increase in spatial resolution of functional imaging…
