Figure 3.

Relative cortical growth from P14 to P21 and P21 to P28. (A) Relative cortical growth increases as a function of relative geodesic distance from the origin of the TNG values for both hemispheres of both ferrets were plotted on the same figure. The increase in slope is larger from P14 to P21 than from P21 to P28. (B) Relative cortical growth from P14 to P21 (left) and P21 to P28 (right) in the left hemisphere of ferret A.1. While we show that the isocortex expands at a roughly constant rate after the identified transitional age Ttr (P12.7), relative cortical growth is larger from P14 to P21 because cortical growth represents the change in local surface area relative to the initial local surface area. Growth was not calculated on the medial wall, which is shown in gray.
