NPY-immuno-expression intensity (mean gray value) was highest in the brain nuclei (HA, HP, TeO, and RoT) during the breeding stage in Northern Spotted Munia. In this study we subtracted the intensity (mean gray value) of the samples in our earlier study to reveal more on the findings of the NPY-in the different life history stages of the bird. There has been a correlation discovered between the expression of NPY and the production of hormones, i.e., NPY found within the HP and hypothalamo-pituitary-gonad (HPG) gland axis of birds to be related to reproductive hormones. ![]() ![]() In a previous study we observed higher NPY immuno-staining in the mating phase of Spotted Munia. NPY-ir cells observed in nuclei associated with vision (HA, HP, and TeO regions of the brain), was intriguing since studies in the past have implicated that NPY in many non-visual functions. The immunoreactivity observed in the regions of the brain wanted to be elucidated. ![]()
