Reviewer's note

The significant amount of language-related functions that have been associated with BA47, such as semantic processing, phonological processing, semantic encoding, and others, is surprising. In these cases, BA47 is simply one of the multiple steps in the brain language processing network. It could be further speculated that in these verbal related functions, the inferior frontal gyrus may play a more emotional/motivational function. Moreover, anatomically BA47 is adjacent to BA45, a clearly language brain area. BA47 participates in some clearly emotional related activities (e.g., adverse emotional inhibition) and also in executive functions (e.g., deductive reasoning).
