A preparation has been developed in the dog which allows recording the electrical activity from an olfactory nerve twig containing the axons of a small group of olfactory receptor cells. The dog's response to n-pentyl acetate is vigorous and stable, like that of other air-breathing animals. The dog's response magnitude dependence on the nasal flow rate was noticeable for n-pentyl acetates, but not so great as for n-butyric acid. The response to n-butyric acid strongly depends on the nasal flow. The start of the nasal air flow caused an increase of neural activity, which is called flow response. The results show that the nasal flow rate is a very important factor which determines the response to odors. Methyl p-hydroxybenzoate is known as a dog's pheromone, however, this odor caused the feeble response in the electrical activity of the dog's olfactory receptor cells. The differences may be dependent on several factors.
已在犬类中开发出一种制剂，可用于记录来自包含一小群嗅觉受体细胞轴突的嗅神经小分支的电活动。犬对乙酸正戊酯的反应强烈且稳定，与其他呼吸空气的动物类似。犬对乙酸正戊酯的反应幅度对鼻气流速率的依赖性较为明显，但不如对丁酸的依赖性那么大。对丁酸的反应强烈依赖于鼻气流。鼻气流的开始会引起神经活动增加，这被称为气流反应。结果表明，鼻气流速率是决定对气味反应的一个非常重要的因素。对羟基苯甲酸甲酯被认为是犬的一种信息素，然而，这种气味在犬嗅觉受体细胞的电活动中引起的反应较弱。这些差异可能取决于几个因素。
