Auditory cortex stepwise functional connectivity. Auditory cortex SFC analysis showed dense connections within the local auditory-related regions, strong direct connectivity with OP4 (a; inset, star) and, to a lesser extent, to the LOTJ (b). To better visualize the degree of connectivity, conventional (bottom inset) and inflated projections (top inset) of the results using a relaxed color-scale threshold and centered on the insula region (green square) are presented in the one-step and three-step maps. In the subsequent steps, auditory connectivity reached the multimodal network (c–f) and the cortical hubs. PCS, Posterior central sulcus; SMA, supplementary motor area.
