To determine the influence on play fighting of inputs to the brain that arise in or course through the olfactory bulbs juvenile male and female rats were bilaterally bulbectomized at 23 or 24 days of age. The frequency of play fighting and play initiation was observed in tests conducted in the home cage. Bulbectomy did not affect the frequency of play fighting or play initiation by males, but slightly increased the frequency of play fighting without altering play initiation in females. Since peripheral anosmia has only modest effects on play fighting, neither the chemosensory nor the modulatory influences of the olfactory bulbs on limbic system activity appear to be especially important in the control of play by juvenile rats.
为了确定起源于嗅球或通过嗅球传导至大脑的输入对幼龄大鼠打闹行为的影响，在23或24日龄时对幼年雄性和雌性大鼠进行双侧嗅球切除。在笼内测试中观察打闹行为的频率和发起打闹行为的频率。嗅球切除并未影响雄性大鼠打闹行为的频率或发起打闹行为的频率，但在不改变雌性大鼠发起打闹行为频率的情况下，轻微增加了其打闹行为的频率。由于外周嗅觉丧失对打闹行为只有适度影响，嗅球对边缘系统活动的化学感应或调节影响在幼年大鼠玩耍行为的控制中似乎都不是特别重要。
