| 摘 要： | 对鸣禽燕雀前脑、中脑和延髓的四个发声控制核团进行了测量。结果发现：前脑ＨＶ＿ｃ，ＲＡ核团的体积存在着明显的性别差异，雄鸟核团均大于雌鸟。中脑ＩＣ＿ｏ核与延髓的ＩＭ核无明显性双态性。这表明，造成燕雀鸣啭能力的性别差异主要是由前脑高位中枢的性双态所决定的。

| Abstract: | our vocal-control nuclei were studied in Fringilla montifringilla. The results show that HVc developed well in male than in female, the volume of RA is much larger in male than in female.There is less sexual differences in the volumes of ICo and IM.This structual differences of vocal-control nuclei may be result in the sexual differences of singing behaviour.HVc and RA,which are loctated in forebrain, play an important role in song learning. |
