Figure 4. Frontal thick sections through the telencephalon of adult Xenopus, from rostral (left) to caudal (right) levels, hybridized for xEmx1 (A–C), xEomes (E–G), or xNkx2.1 (D). Note the strong periventricular expression of xEmx1 in the majority of the pallium (medial, dorsal, and lateral divisions), except the ventral pallium (VP; A–C). The posterolateral amygdalar nucleus (PLA) also shows strong xEmx1 signal (C). Strong xEomes expression is observed in the mitral cell layer of the olfactory bulb (ml; E), as well as in the eminentia thalami (ET; G). However, this gene is apparently downregulated in the pallium of the adult frog (E–G). Note the expression of xNkx2.1 in the pallidal telencephalic domain of adult Xenopus (D), and also note that a major part of the medial amygdalar nucleus does not show any periventricular xNkx2.1 signal. See text for more details. For abbreviations , see list. Scale bar = 200 μm in A (applies to all). |
