摘要:

本文就大熊猫脑的形态结构与美洲黑熊和浣熊脑做了比较研究,提供了新的和更详尽的资料。在外形方面,大熊猫脑有6项熊样特征,4项浣熊样特征,但也有8项它本身独具的形态特点。脑量和体重之间变量关系的研究说明大熊猫脑比黑熊和浣熊有(1)较高的端脑化和新皮质化;(2)较高的小脑进化程度。这些对大熊猫在食肉目中分类地位的讨论具有十分重要的意义。

Abstract:

The present paper gave a new and more detailed account of the exter-nal morphology and internal struc-tures of the brain of the Giant Pa-nda(Ailuropoda melanoleuca)in comparison with those of two rela-ted carnivores,the North Americ-an black bear(Ursus americanus) and the raccoon (Procyon lotor). There are many differences in the external features of some important gyri and lobes.The panda brain sh-ows 6 bearlike and 4 raccoonlike fea-tures,but it also presents 8 impor-tant characteristic features of in own which need to be exphasized in view of the discussions that are now being held about the status of the panda within the carnivores.As far as the allometric relationship betw-een brain size and body size is co-ncerned the main observation is th-at of an evolutionary trend towards (1)higher encephalization and neo-corticalization,(2)higher cereb-ellar progression,in the panda th-an in the other two species.
