The effect of mating behavior on the expression of Fos protein was analyzed within the chemosensory pathways of the male Syrian hamster brain. Following a single mating test, the number of Fos-immunoreactive (Fos-ir) neurons increased within the amygdala, bed nucleus of the stria terminalis and medial preoptic area. The mating-induced pattern of Fos expression within these brain regions shows a strong correlation with the sites of lesions that eliminate or alter mating behavior. In addition, Fos expression was increased within the paraventricular nucleus of the hypothalamus. These results provide the first demonstration of a dynamic and selective pattern of neuronal activity within specific nuclei known to be essential for mating behavior in the male Syrian hamster.
在雄性叙利亚仓鼠大脑的化学感应通路中，分析了交配行为对Fos蛋白表达的影响。经过单次交配测试后，杏仁核、终纹床核和内侧视前区中Fos免疫反应性（Fos-ir）神经元的数量增加。这些脑区中交配诱导的Fos表达模式与消除或改变交配行为的损伤部位显示出强烈的相关性。此外，下丘脑室旁核内的Fos表达也增加了。这些结果首次证明了在已知对雄性叙利亚仓鼠交配行为至关重要的特定核团内，存在动态且选择性的神经元活动模式。
