Figure 4

Sensitivity of (a) growth , (b) elastic volume stretch Je, (c) gyral wavelength λ, and (d) gyrification index GI for varying initial cortical thickness tc. Increasing the initial cortical thickness increases the gyral wavelength and decreases the gyrification index: Folds become longer and more shallow.
