Fig. 5.

Comparison of the mean spatial transformation needed to align native brains to the template brain, separately for V1 (A), V2 (B), and V3 (C). Each dot denotes for a given twin pair the mean Euclidean distance between native vertices in a region and their location after cortical alignment. The solid lines denote the best fitting linear regression and the shaded regions shows the 95% confidence interval. Red: MZ. Blue: DZ.
