Figure 2. Schematic and model geometry of the developing ferret brain.

Figure 2

(a,b) Schematic of coronal section of ferret brain at postnatal day 6 (a) and 14 (b). Drawings were modified based on the tracings of ferret brain sections in Smart and McSherry (1986b). The ferret brain consists of four major layers: (I) cortex, (II) subplate, (III) subcortical white matter (WM), and (IV) deep grey matter (dGM). (c) Representative 2-D finite element model for a brain section before folding. The geometry is partitioned into the four major layers I-IV, each composed of triangular mesh elements. To simulate phased differential growth, a quarter of the cortex and corresponding subplate regions are further divided into two regions (labelled 1 and 2).
