Figure 1. Photomicrographs of Nissl-stained sagittal (A,D,G) and transverse (B,C,E,F,H,I) sections through the basal hypothalamus of a late embryo (A–C), a premetamorphic larva (D–F), and a prometamorphic larva (G–I) at the approximate levels indicated on the respective schemes of the left column. Note that the coordinate system for the hypothalamus rotates 90° because the longitudinal axis of the brain bends in the diencephalon, and this is also the case for all photomicrographs of sagittal sections in all figures. These photomicrographs illustrate the poorly segregated regions in the basal hypothalamus and the scarce cell migration from the periventricular lining during development. The dashed lines in (A,D,G) indicate the approximate boundaries between hypothalamic and diencephalic regions, whereas in (H,I) they also indicate the approximate boundaries of the thalamus, prethalamus, and pretectal diencephalic regions. Scale bars = 200 μm (in C,F,I are valid for B,E,H, respectively)
