Anatomic organization of auditory cortex and the location of the pitch-center (adapted from Bendor and Wang, 2006). (A) An enlarged view of the superior temporal gyrus (STG) of marmoset, showing the core, belt, parabelt areas and the location of the pitch-center. The borders between each auditory area are estimated based on data from Bendor and Wang (2005) and Pistorio et al. (2004). (B) An enlarged view of HG in humans. A1 is presumed to occupy the medial portion of HG (with variability between subjects). The location of neighboring areas (R, pitch-center, lateral belt) is an approximation based on Schneider et al. (2005); Formisano et al. (2003); and Patterson et al. (2002). Legend: HG-Heschl’s gyrus, STG-Superior temporal gyrus, ITG-Inferior temporal gyrus, aSTG-Anterior superior temporal gyrus, PT-Planum temporale, SI-Intermediate sulcus, HS-Heschl’s sulcus, CS-Circular sulcus, FTS-First transverse sulcus, LS-Lateral sulcus, STS-Superior temporal sulcus, A1-Primary auditory cortex, R-Area R (rostral auditory cortex), RT-Area RT (rostrotemporal auditory cortex).
