Altered Brain Activity and Functional Connectivity in Unilateral Sudden Sensorineural Hearing Loss

Figure 2

Intergroup comparisons of voxel-wise FC between the SSNHL and HC groups. Compared with the HC group, the SSNHL group showed significantly increased voxel-wise FC values in nine ROIs, including (a) the lSTG.p and a cluster located in the left putamen and left caudate nucleus, (b) the rSTG.p and a cluster located in the left putamen and left caudate nucleus, (c) the rMTG.p and a cluster located in the bilateral lingual gyri and the right calcarine cortex, (d) the lSMG.a and a cluster located in the left inferior frontal gyrus, (e) the lAG and a cluster located in the bilateral calcarine cortex and left posterior cingulate cortex, (f) the lLG and three clusters located in the right cerebellum posterior lobe, left caudate nucleus, and left MFG, (g) the rLG and two clusters located in the right cerebellum posterior lobe and left MFG, (h) the lPT and a cluster located in the left caudate nucleus and left putamen, and (i) the lOP and a cluster located in the left caudate nucleus and left putamen. The color bar indicates the -value of voxels with significant intergroup differences. STG: superior temporal gyrus; MTG: middle temporal gyrus; SMG: supramarginal gyrus; AG: angular gyrus; LG: lingual gyrus; PT: planum temporale; OP: occipital pole; l: left; r: right; a: anterior division; p: posterior division.
