A rather complex level of language processing is found in BA21 (e.g., selective processing of text and speech and semantic processing). It also participates together with BA22 in processing complex sounds. Its activation along with BA45 when observing motion (mirror neurons?) seems intriguing. In the “attribution of intentions to others” paradigm, a rather extensive activation was observed: BA9/17/18/19/20/21/22/37/38/47; activation of language areas may suggest a verbal mediation.
