Abstract:

The first NPY-immunoreactivity (ir) in the central nervous system of Rhinella arenarum was obtained just after hatching in the pre-optic area, ventral thalamus and rostral rhombencephalon. During pre-metamorphosis, new NPY-ir cells were observed in other brain areas such as pallium, septum and striatum, infundibulum and pars intermedia of the pituitary. Further maturation continued through pro-metamorphosis with the appearance of cell groups in the diagonal band, amygdala, pre-optic nucleus, dorsal nucleus of the habenula, anterior ventral and dorsal thalamus, suprachiasmatic nucleus, tuberculum posterior, tectum, torus semicircularis, inter-peduncular nucleus and median eminence. During the metamorphic climax and soon after, the relative abundance of NPY-ir fibres decreased in all hypothalamic areas and the staining intensity and number of NPY-ir cells in the pallium also decreased, whereas no cells were found in the striatum, dorsal nucleus of the habenula and tectum. In the olfactory epithelium, nerve or bulb, neither cells nor NPY-ir fibres were found during the stages of development analysed. The ontogeny pattern of the NPY-ir neuronal system in the brain of Rh. arenarum is more similar to the spatiotemporal appearance reported for Rana esculenta than to that reported for Xenopus laevis. Many NPY-ir fibres were found in the median eminence and in the pars intermedia of the pituitary, supporting the idea that this neuropeptide may play a role in the modulation of hypophyseal secretion during development. © 2008 Blackwell Verlag GmbH.
