Figure 4

Using MFCSC to detect bilateral pairs where FC asymmetry is indicative of the direction and extent of functional hemispheric dominance. (A) Pairs that had leftward FC asymmetry, i.e. FC[L] > FC[R] (p < 0.00006; Bonferroni corrected with alpha set to 0.05), with colour intensity indicating FC strength, and other conventions as in Fig. 3. (B) Excluding connections with mFCSC[L] ≠ mFCSC[R] (connections to exclude correspond to the top row of Fig. 3, which is reproduced within the rectangle). (C) The subset of the pairs in panel A where left and right unilateral connections probably share the same brain function (as mFCSC is not different between hemispheres). In these pairs, FC asymmetry is a good indicator for the direction and magnitude of functional hemispheric dominance. (D–F) Same conventions as (A–C), but for the analysis of pairs that had rightward FC asymmetry.
