【摘要】 为了研究旁嗅叶(Iobus parolfactorius,LPO)的神经纤维联系,采用DiI示踪法追踪投射到LPO的起始核。首先将5%DiI乙醇溶液注射到鸡端脑的LPO,进行逆行追踪,寻找投射到JPO的起始核,初步判断LPO的起始核为HA,AS后,再将DiI颗粒植入离体固定脑的这两个核团,进行顺行追踪。逆行追踪的结果发现,在副高纹状体(hyperstriatumaccessorium,HA),古纹状体(Archistriatum,AS)有神经元被标记。顺行结果发现在LPO有终末出现。这些表明了端脑内的两个核团HA,AS,直接投射到LPO。
【Abstract】 DiI was injected into the lobus parolfactorius(LPO) in invivo telencephalon for retrograde tracing the nuclei originis.The results showed that the neurons had been labeled in HA and AS.Then,DiI was planted into hypertriatum accessorium(HA) and archistriatum(AS) in invitro telencephalon for anterograde tracing after the preliminarily indication that HA and AS were the origins of LPO.After that,the results revealed the labled terminals appeared in LPO.In a word,these results indicated that HA and AS were the projections to LPO.
