Comparisons between the auditory tests using MNI coordinates of local maximum hemodynamic effects (T > 7.0, p < .05 FWE-corrected). The model subtracted activity during the baseline task before comparison. A. Pitch identification activated the intraparietal sulci (red; left x = -36, y = -38, z = 46; right x = 48, y = -42, z = 52) in comparison to pitch discrimination. B. Pitch contour perception led to higher activity in the right superior temporal gyrus (x = 50, y = -20, z = 6) as compared to all other auditory tests (violet); the cluster was more extended to lateral aspects as compared to pitch identification (red) and discrimination (yellow). C. Transversal view on z = -8. Pitch contour perception (red) and discrimination (green; yellow = both tests) activated the hippocampus (x = ± 32, y = -32) and the rostral anterior cingulate cortex (x = 2, y = 34) stronger than pitch identification. Pitch contour perception activated the right superior temporal gyrus (x = 36, y = 8) stronger than pitch identification and tone localization (violet = both tests; blue = localization).
