[Effect of hemispherectomy on neuroendocrine responses in birds]

In the thalamic pigeon, neurogenic stimuli were still effective in promoting the adreno-cortical activation. The magnitude of the response was as important as in intact birds and was also similar to that obtained after anterior lateral deafferentation of the hypothalamus. Photically induced testis growth was quite normal in hemispherectomized quail. It appears therefore that in birds two kinds of neuroendocrine responses can be induced without any telencephalic participation.
