Stability of module partitions under variation of spatial resolution parameter γ. Both A and B show the number of modules encountered at each level of γ in the range of 0.5–1.5 (incremented in steps of 0.01), centered around the default value of 1. (A) Of the six solutions encountered for association (unilateral) connections only, that with three modules was the most stable (and fully homogeneous) over the widest range of γ. B plots the number of modules encountered when association and commissural connections are considered together. Here, four solutions are encountered, with the most stable having six modules, three in each hemisphere. The three are identical in each hemisphere and are identical to the three modules identified in the single hemisphere analysis (A). The bilateral six-module solution was adopted for the remainder of the study.
