Functional connectivity maps for a seed region in right anterior insula (RAI). Rows 1 and 2 show, respectively, random effect functional connectivity t-maps  for controls and tinnitus displayed on inflated views of the PALS-B12 atlas surface . The distribution of positive and negative correlations between time courses in the seed vs. other brain locations painted, respectively, in yellow-orange and blue (scale: p value 0.05-0.005). Row 3 shows map of a t-test assessment per node of group differences in Fisher Z-transforms of correlations. Significant t-test results marked in yellow-orange for positive and blue for negative (scale: p value 0.05-0.002). Black borders surround significant cluster identified with the threshold free cluster extension analysis  after 5000 permutations of the t-test analysis and an alpha threshold < .05.
