我们研究了25组基因不同的小鼠海马锥体内和锥体下苔藓纤维（iip-MF）终端场的大小和对新环境（开放场地）的适应。基于先前的研究结果和理论考虑，预计iip-MR终端场的大小与随后两次暴露于开放场之间的行为改变程度之间存在正相关关系。事实上，因子分析揭示了这种关系。结果表明，具有大iip-MF终端场的小鼠在空间信息处理方面效率更高。
We studied the sizes of the hippocampal intra- and infrapyramidal mossy fiber (iip-MF) terminal fields and habituation to a new environment (open-field) in 25 genetically different groups of mice. Based on previous findings and theoretical considerations, a positive relationship between the size of the iip-MR terminal fields and the extent of behavioral change between two subsequent exposures to the open-field was expected. In fact, such a relationship was revealed by a factor analysis. Our results indicate that mice possessing large iip-MF terminal fields are more efficient in the processing of spatial information.
