豚鼠被允许研究含有罗丹明（一种非挥发性荧光染料）的尿液。自由接触染色尿液的豚鼠在犁鼻器和隔器官中显示荧光，但在嗅上皮中没有。当呈现未掺杂的尿液时，未观察到荧光。因此，挥发性低的化合物，不能到达嗅觉上皮，可以刺激犁鼻系统，并提供通常不能由味觉或嗅觉提供的信息。
Guinea pigs were allowed to investigate urine that contained rhodamine, a nonvolatile fluorescent dye. Guinea pigs given free access to dyed urine exhibited fluorescence in their vomeronasal and septal organs but not on their olfactory epithelium. Fluorescence was not seen when unadulterated urine was presented. Thus compounds of low volatility, which do not reach the olfactory epithelium, may stimulate the vomeronasal system and provide information that is normally not provided by gustation or olfaction.
