本章要探讨的假设是基于这样的假设,即后顶叶皮质(PPC)直接参与代表与空间信息处理相关的空间特征的子集,并在知觉记忆以及空间信息的长期记忆编码、巩固和提取中发挥重要作用。在介绍了大鼠PPC的解剖位置后,讨论了基于单一空间特征的PPC表征的性质,与视觉空间注意相关的视觉特征的绑定,与关联的获得和存储相关的客体-位置关联的绑定,其中一个元素是空间成分的关联的绑定,以及长时记忆中表象信息和异形信息的绑定。此外,还提供了购买力平价在空间信息长期存储中的中介作用的证据。最后,从系统和动态的角度提出了PPC与海马体的关系。
The hypothesis to be explored in this chapter is based on the assumption that the posterior parietal cortex (PPC) is directly involved in representing a subset of the spatial features associated with spatial information processing and plays an important role in perceptual memory as well as long-term memory encoding, consolidation, and retrieval of spatial information. After presentation of the anatomical location of the PPC in rats, the nature of PPC representation based on single spatial features, binding of visual features associated with visual spatial attention, binding of object-place associations associated with acquisition and storage of associations where one of the elements is a spatial component, and binding of ideothetic and allothetic information in long-term memory is discussed. Additional evidence for a PPC role in mediation of spatial information in long-term storage is offered. Finally, the relationship between the PPC and the hippocampus from a systems and dynamic point view is presented.
