Caudal-to-rostral subdivisions of anatomically defined Heschl's gyrus. a, Human primary auditory cortical areas Te1.2, 1.0, and 1.1 along the rostrolateral to caudomedial extent of Heschl's gyrus, shown in diagram form (Morosan et al., 2001). b, To approximate these regions, anatomical Heschl's gyrus ROIs drawn on individual structural brain images were parcellated into three rostral-to-caudal divisions, illustrated here at 30% overlap between participants as a three-dimensional representation. c, Axial slices illustrating subdivisions at 30% overlap across participants. d, Signal change relative to the resting fixation baseline was extracted from each individual participant's Heschl's gyrus subregion, contralateral (Contra) and ipsilateral (Ipsi) to stimulation, for each block type. The deaf had a larger somatosensory and bimodal response across all Heschl's gyrus regions, and the difference between deaf and hearing adults was larger for somatosensory and bimodal stimuli than for visual stimuli.
