The main connectivity revealed by the extent and intensity of the principal clusters with expressive areas makes evident that BA46 basically participates in a language production system, which also includes BA44, BA45, BA47, and BA6 in the left frontal lobe. This system could be referred as the "frontal language production system", or simply, the "Broca's system" and in the current study it presents very small co activation with other brain areas.
