为了测试顶叶皮层和海马体对异中心空间线索记忆的贡献，作者对大鼠进行了进行/不进行任务的训练，该任务要求大鼠记住两个视觉线索之间的距离。整个海马损伤损害了异中心距离的工作记忆表征，而顶叶皮层损伤仅导致短暂的损伤。在第二个实验中，海马和顶叶皮层损伤均未损害异中心距离辨别力。第三个实验表明，海马结构的背侧和腹侧区域都必须被破坏，以损害异中心距离信息的工作记忆。在调节异中心距离信息的记忆中，海马体和顶叶皮层之间似乎存在分离。（PsycINFO 数据库记录 (c) 2016 APA，保留所有权利）
To test for the contribution of the parietal cortex and hippocampus to memory for allocentric spatial cues, the authors trained rats on a go/no-go task that required the rat to remember the distance between two visual cues. Total hippocampal lesions impaired working-memory representation for allocentric distance, whereas parietal cortex lesions resulted in only a transient impairment. In a second experiment, neither hippocampal nor parietal cortex lesions impaired allocentric distance discrimination. A third experiment showed that both the dorsal and ventral areas of the hippocampal formation must be destroyed to impair working memory for allocentric distance information. There appears to be a dissociation between the hippocampus and parietal cortex in mediating memory for allocentric distance information.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
