Pregnant rats received 2-[14C]deoxy-D-glucose (2DG) intravenously on the last day of gestation, and their fetuses were delivered 1 hour later by cesarean section. Fetal brains showed high 2DG uptake spread throughout the accessory olfactory bulb and little or no differential uptake in the main olfactory bulb. These findings demonstrate that functional activity occurs in the accessory olfactory bulb in utero and suggest that the accessory olfactory system may be the pathway by which fetal rats detect the odor quality of their intrauterine milieu.
妊娠大鼠在妊娠最后一天静脉注射2-[¹⁴C]脱氧-D-葡萄糖（2DG），1小时后通过剖宫产取出胎儿。胎儿大脑显示2DG摄取量高，分布于整个副嗅球，而主嗅球摄取量差异很小或无差异。这些发现表明，子宫内副嗅球存在功能活动，提示副嗅觉系统可能是胎鼠检测其子宫内环境气味质量的途径。
