Expression of pcdh19, pcdh17 and cdh6 in habenular, pretectal, dorsal thalamic, ventral thalamic, anterior thalamic and preglomerular nuclei. Images in top panels show low magnifications of adjacent brain sections from a level shown in Figure 1. D and E are higher magnifications of the habenular, ventral thalamic and pretectal regions of their respective images in the top panels. F and G are higher magnifications of the preglomerular nuclei, while H and I are magnified views of the anterior hypothalamus shown in the top panels. See the list for abbreviations. Scale bar = 200 μm for the top panels, 50 μm for the lower panels (F–I have the same magnification).
