This study analyzed the effects of deafferentation of the main, vomeronasal or both olfactory systems on the agonistic behavior of male mice in response to unfamiliar male intruder mice. In every animal, regardless of the technique used, disruption of the vomeronasal system led to consistent reductions in agonistic behavior. All animals receiving bulbectomies, vomeronasal tract transections or a combined treatment of vomeronasal cuts and ZnSO4 nasal flush reliably suppressed agonistic responding toward the intruder. Animals treated with intranasal ZnSO4 alone or those receiving control procedures continued to respond to the intruders at rates similar to pretreatment. These results indicate that the vomeronasal system is directly involved in the perception of the male chemosignals modulating agonistic behavior and, therefore, is capable of modulating the male's response to these signals.
本研究分析了主要嗅觉系统、犁鼻器系统或二者同时去传入神经对雄性小鼠针对陌生雄性入侵者的攻击行为的影响。在每只动物中，无论采用何种技术，犁鼻器系统的破坏都会导致攻击行为持续减少。所有接受嗅球切除术、犁鼻器神经束横断术或犁鼻器切断与硫酸锌鼻腔冲洗联合治疗的动物，对入侵者的攻击反应均得到可靠抑制。单独接受鼻内硫酸锌治疗的动物或接受对照程序的动物，对入侵者的反应率仍与预处理时相似。这些结果表明，犁鼻器系统直接参与调节攻击行为的雄性化学信号的感知，因此能够调节雄性对这些信号的反应。
