We used functional magnetic resonance imaging to investigate the areas activated by signed narratives in non-signing subjects naïve to sign language (SL) and compared it to the activation obtained when hearing speech in their mother tongue. A subset of left hemisphere (LH) language areas activated when participants watched an audio-visual narrative in their mother tongue was activated when they observed a signed narrative. The inferior frontal (IFG) and precentral (Prec) gyri, the posterior… CONTINUE READING
