Fig. 1.

The low power view of normal neocortex (NeuN, ×40) and a Korean folding pan (inlet). The imaginary white lines show the direction of radial migrations of neural cells. The lines look like the bones of a folding pan (inlet). The cortical six-layers were seen with red imaginary lines. The red imaginary lines show the tangential composition of neocortex. In the normal neocortex, it is unusual that the neuronal cells exactly align along the white imaginary lines.
