Our analysis pipeline parcellated the human auditory cortex into three clusters, the central and two other flanking parts. Each cluster exhibited a distinct functional connectivity pattern indicating its contribution to different functional networks.
Fig. 2: Parcellation results of the primary auditory cortex for (a) left and (b) right hemisphere. Cluster 1 (black) showed the strongest SC to STG. Cluster 2 (green) was located in gyrus part of HG. Cluster 3 (red) showed strong SC to insula.
Fig. 3: T-values for regions with significantly different mean FC visualized in the atlas space. Positive t-values are presented as red color which implies the mean FC values in a pair of regions satisfy cluster1 > cluster3. Negative t-values are presented as blue color which implies the mean FC values in a pair of regions satisfy cluster1 < cluster3. The seed is located in (a) the left hemisphere and (b) the right hemisphere, respectively.
