Localization of GFP expression in the rat ARC and AVPV. Neuroendocrine cells are shown by GFP-staining (green). Representative images showing GFP distribution in the ARC a and c and AVPV b and d after intra-ARC administration are shown. Representative images showing GFP distribution in the AVPV e and g) and ARC f and h after intra-AVPV administration are also shown. ARC, Arcuate nucleus. AVPV, Anterior ventral paraventricular nucleus. Three V, the third ventricle. ac, anterior commissure. VMPO, ventromedial preoptic nucleus. ME, Medial eminence. The red arrows represent the corresponding images at high magnification. The blue arrow refers to the 3 V. Scale bars, 1 mm a, b, e and f). Scale bars, 500 μm (c, d, g and f
