a The intraparietal sulcus (IPS). b The thalamus. Left: axial or coronal view showing brain areas activated during the appearance of deviant tones. The upper legend shows the t-values associated with the color map. Results are thresholded at p < 0.05 FDR-corrected. The blue arrow is pointing at either the bilateral intraparietal sulcus (peak MNI coordinates left hemisphere: [−40 −46 50], Zscore = 4.16, PFDR-corr = 0.002; right hemisphere: [45 −30 51], Zscore = 3.47, PFDR-corr = 0.008) or at the bilateral thalamus (peak MNI coordinates left hemisphere: [−16 −21 11], Zscore = 4.61, PFDR-corr = 0.001; right hemisphere: [17 −20 12], Zscore = 4.45, PFDR-corr = 0.002). Center: probabilistic ROIs across subjects overlapped onto the activation map for both ROIs. The color scale showed in the lower legend represents the proportion of subjects whose ROI included that node: the redder the color the higher the probability that the node is common across the subjects. Right: an example of the adjusted eigenvariate in both ROIs. c Thalamic probability maps on parcellation. Left: Zoom in of the thalamic probability maps overlapped onto an MRI-based parcellation of the thalamus21 in all three views. Right: Parcellation alone to fully show the nuclei encompassing our thalamic activation.
