Presentation dorsal-ventral boundaries at the rostral and caudal mesodiencephalon during development.

<p>(A) Schematic coronal representation of the dorso-ventral organization of the floor plate (FP), basal plate (BP) and alar plate (AP). (B) Nissl stained E13.5 coronal section for the anatomical orientation. The floor-basal and basal-alar boundaries are shown in red dashed lines. (C) Schematic representation of a sagittal section showing the position of the coronal sections shown in G and F. The position of DA neurons are depicted in grey. (D–G) In situ hybridisation for Th, Pitx3, Aadc and Nurr1 on E12.5 (D), E13.5 (E), anterior E14.5 (F) and posterior E14.5 coronal sections (G). Abbreviations: Aq, aqueduct; F, forebrain; H, hindbrain; M, midbrain; MHB, mid/hindbrain border.
