(A,C,D) Dorsal view (A: HH 30; C: HH24; D: HH23). (B) Horizontal section of
the level indicated by white line on A.(D) Whole mount in situ hybridization

border of the tectum at the experimental side locates rostrally to that at the
control side. mes: mesencephalon, is: isthmus, met: metencephalon, fp, floor
