Fig. 2.

Spatial extent of the VA in bilateral AC. a) Voice compared to nonvoice sounds (left panel), and the same contrasts performed for the AEs. Blue activations P < 0.001 (uncorrected); orange activations P < 0.05 [family-wise error (FWE)-corrected]. Black dashed line denotes significant P < 0.05 (FWE) voxels from the original sound contrast, indicating that all significant voxels of AEs are contained within the original VA. White outlines indicate anatomical subparts of the AC, especially primary AC (Te1.0–1.2), secondary AC (PTe), and higher-level AC (Te3). b) The left upper panel shows voxels resulting from the conjunction analysis for which the contrast [voice > nonvoice] exceeds all the analogous contrasts performed on AEs (green dashed line). The individual interaction analyses compare the [voice > nonvoice] contrasts for original sounds against the same contrast in each of the AEs separately (shown in the mid and right upper and all lower panels). L, left; R, right, Te, temporal regions.
