Percentage of GFP-positive areas on the surface (%)	Percentage of GFP-positive areas in the cortical region on the longitudinal section (%)a
17.6 ± 1.2	10.2 ± 1.7

Mean ± SEM (n = 4 biologically independent samples). The percentage of GFP-positive areas was calculated from fluorescence stereomicroscopic images. Representative images are shown in Fig. 2d.

^aCalculation was performed after excluding the areas with reddish medullary rays.
