Figure 9.

Developmental origin of medullary reticular formation glutamatergic neurons. Schematic image modified from Figure 2E (A) or from Figure 2G (G) indicating location of glutamatergic populations of pr8 (B-F) or pr9 (H-K). (B-F, G-K) Images showing inverted VGlut2 mRNA (magenta), βgal (green), and FoxP2 (J1, green) from Dbx1-βgal (B, C, H, I), Lmx1b-βgal (D-F, J2-K) and wild type (J1) mice. Note (J1) and (J2) are from the same region from different animals. Single color images shown to right. VGlut2 (top, brightfield), βGal (bottom). Arrows indicate co-expression. Arrowheads indicate absence of co-expression. Scale bar = 500 μm.
