为了评估自我中心距离和位置信息的工作记忆系统，对每只大鼠运行延迟匹配样本（DMTS）去/不去任务。为了评估参考记忆系统，并作为非记忆缺陷的对照，然后使用相同的大鼠进行连续的辨别go/no-go任务。与海马，但不顶叶皮层，损伤的大鼠相对于控制在工作记忆（DMTS）任务的自我中心的距离和位置信息，虽然赤字观察到的自我中心的距离信息的工作记忆任务与海马病变的大鼠是轻微的。无论是海马或顶叶皮层损伤大鼠受损相对于对照组的参考记忆（连续歧视）任务的任何线索。海马似乎参与了自我中心距离和空间位置信息的工作记忆，而顶叶皮层则没有。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
To assess the working memory system for egocentric distance and place information, delayed matching-to-sample (DMTS) go/no-go tasks were run for each rat. To assess the reference memory system, and to serve as a control for nonmemory deficits, successive discrimination go/no-go tasks were then conducted using the same rats. Rats with hippocampal, but not parietal cortex, lesions were impaired relative to controls in the working memory (DMTS) task for both egocentric distance and place information, although the deficit observed in the working memory task for egocentric distance information by rats with hippocampal lesions was mild. Neither hippocampal nor parietal cortex lesioned rats were impaired relative to controls in the reference memory (successive discrimination) task for either cue. The hippocampus appears to be involved in working memory for egocentric distance and in spatial location information, whereas the parietal cortex is not.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
