The term Broca's area refers to a functionally defined structure that includes portions of the triangular part of the inferior frontal gyrus and the opercular part of the inferior frontal gyrus of the cerebral cortex. Architectonically it corresponds to area 44 and area 45, which constitute the ventrolateral prefrontal cortex ( Petrides-2012 ). Functionally, it is involved in speech production and is identified with the rostral part of ventral premotor cortex (area PMVr in the human; area F5 in the macaque) ( Matelli-2004 ).
