Table 2.

The significance and r² values for the regression analyses, for each of the 5 subregions of the callosum

	CC₁		CC₂		CC₃		CC₄		CC₅
	Significance	r²	Significance	r²	Significance	r²	Significance	r²	Significance	r²
CC vs length	0.194	0.083	0.440	0.030	0.903	0.001	0.982	0.000	0.640	0.011
Connect vs length	0.008	0.304	0.002	0.390	0.015	0.263	0.125	0.114	0.036	0.203

Note: The top row provides the results for regressions of the cross-sectional area of subregion i of the callosum on the average length of the connections passing through subregion i. These values correspond to the regression plots in Figure 4. The bottom row provides the results for regressions of the degree of connectivity—abbreviated here as connect—for subregion i against the average length of the connections in subregion i. These values correspond to the regression plots in Figure 5.
