We investigated the localization of APUD (amine content and amine precursor uptake and decarboxylation) cells and tyrosine hydroxylase (TH)-negative, aromatic L-amino acid decarboxylase (AADC)-positive neurons (D neurons) in the hypothalamus of the bird (Melopsittacus undulatus) and the lizard (Varanus exanthematicus), and compared the differences between the two species, L-DOPA was demonstrated in the paraventricular organ (PVO) which is a characteristic region in the hypothalamus of the bird and the lizard. In the PVO of the grass parakeet, there were a small number of dopamine neurons in addition to APUD cells. However, in the PVO of the lizard, there were APUD cells but no dopamine neurons. Furthermore, TH-negative, AADC-positive neurons (D neurons) were found in the medial part of nucleus arcuatus of the bird, but not of the lizard.
