摘要	本文研究探讨了进化地位不同的三种动物的短时空间记忆功能及其与前额叶背侧部进化水平的相关性。结果表明,在延缓反应作业中,经1000次训练后,7只恒河猴对空间位置的记忆时间平均为7.7±3.2min,懒猴为3.8±0.44min,而树鼩即使在延缓时间几乎为零秒的延缓反应中,其正确反应率也未达到90％标准。一种延缓时间仅测试一个单元,即不经训练的实验表明,恒河猴在延缓期为“0”—5min的各测试单元中,正确反应率稳定在80％以上;懒猴在延缓时间为“0”—4min的各测试单元中,平均正确反应率与恒河猴无明显差异,而当延缓时间增加到5min时,在延缓反应作业中取得的成绩显著下降;树鼩在延缓时间为1—5min的作业中取得的正确反应率在70％以下。3种动物在视觉辨别学习作业中却无明显差异。形态学研究表明,灵长类大脑前额叶的面积和结构的复杂性在进化过程中逐渐增大,如恒河猴大脑前额叶的表面积占大脑半球表面积的11.5％(Brodmann,1929),其内颗粒层发达,背侧部明显凸起,主沟区发达;懒猴的前额叶表面积占其大脑半球表面积的8.3％,背侧部凸起不显著,主沟未形成,额极内颗粒层分化明显,背侧部的内颗粒层较内侧部的发达程度差(Sanides,1967);树鼩的前额叶表面积占7.5％,额极的内颗粒层分化不明显,为非颗粒化区,此区之后为颗粒区. ; The relation between evolution of spatial working memory function and of morphology of the dorsolateral prefrontal cortex among the rhesus monkey (Macaca mulatta),the slow loris (Nycticebus coucang) and the tree shrew (Tupaia belangeri chinensis) were reported in present paper.The results read as follows:In the DR performance with training,the rhesus monkeys and slow lorises could reach a criterion of 90% correct response at 7.7±3.2 seconds,and 3.8±0.4 seconds delay interval,respectively,by 1000 training trails.The tree shrews failed to reach the criterion of 90% correct response even at 0 seconds delay interval by 1000 training trails.If a delay interval was tested in one session (30 trails) only,doing the DR performamce without training,the rhesus monkeys reached a correct of 80% or higher in each session at 0,1,2,3,4,and 5 seconds delya,respectively.The percent correct in each session of the slow lorises showed no differences from the rhesus monkeys at 0,1,2,3,and 4 seconds delay.However,when the delay interval was increased to 5 seconds,the percent correct of the DR performance declined to 70% or lower in the slow lorises.In the tree shrews the percent correct in each session reached to 70% or lower at 0,1,2,3,4,and 5 seconds delay interval,respectively.The morphological studies revealed that the size of the prefrontal cortex increased,and the structure got complex in the course of the evolution in primates.It is suggested that the relation of evolution between the spatial working memory function and anatomy in the prefrontal cortex might be significant among the three species,both the development of morphology and that of the spatial working memory function in the dorsolateral prefrontal cortex are later than other regions of cerebral cortex in phylogenetic evolution course.
