Figure 6. Scatter plots showing correlation coefficient and p-values between gene similarity matrix and structural connectivity, fiber distance and Euclidean distance between gene points.

Figure 6

(A) No correlation is found between the structural connectivity matrix obtained from tractography and the gene correlation matrix (B) A negative correlation coefficient of 0.0722 with a significant p-value =0.001 < 0.05 is found between the square matrix of fiber distances and the gene correlation matrix (C) When the actual Euclidean distance between the gene points in 3D space is taken, a negative correlation of 0.0987 is found with the gene similarity matrix. However, small p-values are probably occurring because of the large number of points in the comparison and hence these results may not indicate a true underlying relationship.
