测试了内侧前额叶皮层或顶叶皮层损伤的动物以及假手术和非手术对照的动物获得邻臂任务的能力，该任务强调了自我中心空间偏侧化的重要性，以及奶酪板任务，该任务强调了异中心空间定位的重要性。结果表明，相对于对照组，内侧前额叶皮层损伤的动物在相邻手臂任务中受损，但在奶酪板任务中表现出促进作用。相反，相对于对照组，顶叶皮层损伤的大鼠在奶酪板任务中受到损害，但在相邻手臂任务中没有表现出损害。数据表明，在自我中心与异中心空间信息编码方面，内侧前额叶皮层和顶叶皮层之间存在双重功能分离。（PsycINFO 数据库记录 (c) 2016 APA，保留所有权利）
Animals with medial prefrontal cortex or parietal cortex lesions and sham-operated and non-operated controls were tested for the acquisition of an adjacent arm task that accentuated the importance of egocentric spatial lateralization and a cheese board task that accentuated the importance of allocentric spatial localization. Results indicated that relative to controls, animals with medial prefrontal cortex lesions are impaired on the adjacent arm task but displayed facilitation on the cheese board task. In contrast, relative to controls, rats with parietal cortex lesions are impaired on the cheese board task but show no impairment on the adjacent arm task. The data suggest a double dissociation of function between medial prefrontal cortex and parietal cortex in terms of coding of egocentric versus allocentric spatial information.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
