Expression pattern of <i>NeuroD1</i> in the juvenile (A2–E2) and adult (A3–E3) <i>X. laevis</i> brains.

<p>A1–E1) Schematic coronal illustrations of the corresponding transverse sections of a juvenile <i>X. laevis</i> brain (NF stage 66). The drawing at the top of the figure shows a dorsal view of the <i>X. laevis</i> brain. The letters correspond to the rostro-caudal location of sections as depicted in the whole brain drawing. Arrows and arrowheads in C2, C3, D2, and D3 highlight less conspicuous areas of labeling. Abbreviations are defined in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066487#pone-0066487-t001" target="_blank">Table 1</a>. The anatomical drawings are from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066487#pone.0066487-Tuinhof1" target="_blank">[55]</a>, with modifications of basal ganglia subdivisions according to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066487#pone.0066487-Marin1" target="_blank">[56]</a>. For all images, dorsal is to the top. Scale bar = 400 µm in A2–E2, and 100 µm in A3–E3.
