Norepinephrine (NE) concentrations were measured in the olfactory bulbs and olfactory cortex of male albino rats and golden hamsters sacrificed 13-16 days after castration or sham surgery. Castration significantly decreased NE concentrations in the olfactory bulbs of rats but not hamsters. Castration had no significant influence on NE levels in the olfactory cortex of either species. Regional brain weights were not influenced by surgery, and previous olfactory exposure had no significant effect on any variable measured. The decrease in rat olfactory bulb NE levels may be involved in castration-induced changes in preferences for conspecific odors.
在阉割或假手术后13 - 16天处死的雄性白化大鼠和金黄仓鼠的嗅球和嗅皮质中测量去甲肾上腺素（NE）浓度。阉割显著降低了大鼠嗅球中的NE浓度，但仓鼠的嗅球中未降低。阉割对两种动物嗅皮质中的NE水平均无显著影响。脑部区域重量不受手术影响，且先前的嗅觉暴露对所测量的任何变量均无显著影响。大鼠嗅球NE水平的降低可能与阉割诱导的对同种气味偏好的变化有关。
