对顶叶皮质(PC)或海马结构(HF)损伤的不同组大鼠进行了Morris水迷宫认知图谱任务的习得和保持测试。每个损伤组的一些动物在任务中接受了术前训练。每组中的其他动物没有接受任何术前训练。结果表明，尽管这两种损伤都导致了任务的习得和保持中的认知映射障碍，但定量测量表明，PC损伤的动物比HF损伤的动物更严重。然而，动物游泳行为的定性方面表明，HF损伤的动物倾向于使用“非映射”策略来解决任务，这表明它们的损伤的定性性质不同于PC损伤的动物。这项研究的结果支持这样一种假设，即PC在处理关于身体外或向外空间的信息方面发挥着重要作用。(心理信息数据库记录(C)2016 APA，保留所有权利)
Separate groups of rats with lesions in the parietal cortex (PC) or hippocampal formation (HF) were tested for acquisition and retention of the Morris water maze cognitive mapping task. Some of the animals in each lesion group received preoperative training in the task. Other animals in each group received no preoperative training. Results indicate that although both lesions lead to a cognitive mapping impairment in both the acquisition and retention of the task, the animals with PC lesions were more severely impaired than were the animals with HF lesions, as indicated by quantitative measures. However, qualitative aspects of the animals' swim behavior indicate that the HF damaged animals tend to use" nonmapping" strategies to solve the task, which suggests that the qualitative nature of their impairment differs from that of the PC damaged animals. Results of this study support the hypothesis that PC plays an important role in the processing of information about space that is allocentric or external to the body.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
