In female prairie voles (Microtus ochrogaster) bilateral olfactory bulbectomy reduced affiliative behavior, as measured by social contact, and prevented the formation of partner preferences. Unilateral olfactory bulb removal did not significantly influence affiliative behavior, but did inhibit partner preferences. Bilateral, but not unilateral, bulbectomy significantly reduced the proportion of females exhibiting behavioral estrus following male exposure. In contrast to affiliative and sexual behavior, parental behavior was not significantly affected by either bilateral or unilateral olfactory bulbectomy. These results suggest that divergent sensory-neural pathways underlie social, sexual, and parental behaviors in this species.
在雌性草原田鼠（Microtus ochrogaster）中，双侧嗅球切除会减少通过社交接触衡量的亲和行为，并阻止伴侣偏好的形成。单侧嗅球切除对亲和行为没有显著影响，但会抑制伴侣偏好。双侧而非单侧嗅球切除显著降低了雌性在接触雄性后表现出行为性发情的比例。与亲和行为和性行为不同，双侧或单侧嗅球切除对亲代行为均无显著影响。这些结果表明，该物种的社交、性和亲代行为有着不同的感觉神经通路作为基础。
