Functional connectivity between the auditory cortex and the V5/MT cortex was strengthened when deaf subjects performed visual rhythm discrimination. (A) Visual regions showing increased functional coupling with the high-level auditory cortex during visual rhythm processing relative to visual control in deaf subjects vs. no effect in hearing subjects (PPI analysis, between-group comparison). The analyses for the left and the right auditory cortex were performed separately. The seed regions (depicted in green) were defined based on an anatomical atlas. LH, left hemisphere. (B) The results of an ROI analysis, based on V5/MT anatomical masks. Thresholds: (A) P < 0.001 voxelwise and P < 0.05 clusterwise. The analysis was masked with the visual cortex anatomical mask. (B) t, trend level, P < 0.1; *P < 0.05; **P < 0.01; ***P < 0.001. Error bars represent SEM.
