Voxels whose activation is sensitive to the envelope modulation rates of sentences, scrambled sentences, and melodies, respectively, p < .005. Voxels sensitive to both sentences’ and scrambled sentences’ rates are also displayed (yellow). B. Voxels whose activation is more sensitive to the envelope modulation rate of the sentences than the scrambled sentences (red), more sensitive to the envelope modulation rate of sentences than melodies (blue), respectively, p < .005. Regions of overlap for the two contrasts are also displayed (yellow).
