Areas and pathways subserving object and spatial vision are segregated in the visual system. Experiments show that the primate prefrontal cortex is similarly segregated into object and spatial domains. Neurons that code information related to stimulus identity are dissociable, both by function and region, from those that code information related to stimulus location. These findings indicate that the prefrontal cortex contains separate processing mechanisms for remembering "what" and "where" an object is.
在视觉系统中，负责物体视觉和空间视觉的区域及通路是分开的。实验表明，灵长类动物的前额叶皮层同样被分为物体和空间两个区域。编码与刺激物身份相关信息的神经元，在功能和区域上都与编码与刺激物位置相关信息的神经元不同。这些发现表明，前额叶皮层包含用于记忆物体“是什么”和“在哪里”的独立处理机制。
