Fig. 7. Dispersion of DiD-labelled GFP neurons in the MZ after the DiD injection into the frontal or occipital cortex, three days after injection (E18.5). (A,B) Dorsal view of the area around the injection site. Injection was made into the frontal (A) or occipital (B) cortex. Inset diagram illustrates the position of the injection site. (C,D) Distribution of DiD-labelled GFP neurons after injection into the frontal (C) or occipital (D) cortex. Circles show the positions of DiD-labelled GFP neurons 1 mm from injection site. Each graph represents pooled data from two independent experiments. The lack of data in regions rostromedial (A,C) or caudomedial (B,D) to the injection site is due to folding of the cortex. R, rostral; C, caudal; L, lateral. Dotted lines show the flat-mount outline. Scale bars: 500 µm.
