The morphological analysis of the neural circuit about initial analysis zone of the pheromone information.

我们分析了小鼠副嗅球（AOB）和脑室下区（SVZ）成体神经发生的树突状细胞的组织学特征和组织化学特征。与主嗅球（MOB）一样，AOB的JG细胞表达GABA、酪氨酸羟化酶或钙结合蛋白。此外，SVZ引起神经元迁移到邻近的AOB靶区。这些结果表明，犁鼻系统的维持机制与主嗅觉系统基本相同，但神经分析系统不同。

We analyzed that the histological properties of the dendritic form and the histochemical characteristics of the juxtaglomerular cells (JG cells) in the mouse accessory olfactory bulb (AOB), and those adult neurogenesis in the subventricular zone (SVZ) after birth periods. As same as the main olfactory bulb (MOB), JG cells of the AOB express GABA, tyrosine hydrocxylase or calcium-binding proteins. Moreover, SVZ give rise to neurons that migrate to adjacent target zones of AOB. Those findings suggested that the maintenance mechanism of the vomeronasal system is almost the same with main olfactory system, but the neural analysis systems were different each other.
