Prairie voles (Microtus ochrogaster) are social rodents that show characteristics of monogamy including high levels of social behavior and male parental care. Behavioral studies of prairie voles have implicated chemosignals in the control of various components of social behavior and reproduction. In the present study, the role of the olfactory system in male behavior was examined following surgical removal of the olfactory bulbs. Decreases in measures of sexual, paternal, and other social behaviors were observed following bilateral olfactory bulbectomy, but not unilateral or sham bulbectomy. Some bilaterally bulbectomized males also showed a stereotypy, but this probably did not account for the changes in social behaviors.
草原田鼠（Microtus ochrogaster）是群居啮齿动物，表现出一夫一妻制的特征，包括高水平的社交行为和雄性亲代抚育行为。对草原田鼠的行为研究表明，化学信号参与了社交行为和繁殖各个组成部分的调控。在本研究中，通过手术切除嗅球来研究嗅觉系统在雄性行为中的作用。双侧嗅球切除术后，观察到性行为、父性行为和其他社交行为的指标有所下降，但单侧或假手术切除嗅球后则未出现这种情况。一些双侧嗅球切除的雄性也表现出刻板行为，但这可能无法解释社交行为的变化。
