Neuronal differentiation gene expression also follows a cordal pattern. a DAPI nuclear labeling illustrates the external morphology of the embryo at stage 8. The dotted line indicates the positioning of the cross sections presented in Fig. 8. b and c Expression of NEUROG (b) and NEUROD (c) at stage 8 shown with wholemount in situ hybridization. All pictures are dorsal views and the mouth is at the top. sp, subpedunculate tissue (juxtaganglionic tissue). See abbreviations as in Figs. 2 and 5. Scale bar: 500 μm (a)
