About 25 years ago, the discovery of receptive field (RF) remapping in the parietal cortex of nonhuman primates revealed that visual RFs, widely assumed to have a fixed retinotopic organization, can change position before every saccade. Measuring such changes can be deceptively difficult. As a result, studies that followed have generated a fascinating but somewhat confusing picture of the phenomenon. In this review, we describe how observations of RF remapping depend on the spatial and temporal sampling of visual RFs and saccade directions. Further, we summarize some of the theories of how remapping might occur in neural circuitry. Finally, based on neurophysiological and psychophysical observations, we discuss the ways in which remapping information might facilitate computations in downstream brain areas.

Perisaccadic 重映射：什么？如何？为什么？

大约 25 年前，非人类灵长类动物顶叶皮层中感受野 (RF) 重映射的发现表明，人们普遍认为视觉 RF 具有固定的视网膜组织，可以在每次扫视之前改变位置。衡量这些变化可能非常困难。结果，随后的研究对这一现象产生了一幅迷人但有些令人困惑的图景。在这篇综述中，我们描述了 RF 重新映射的观察结果如何取决于视觉 RF 和跳视方向的空间和时间采样。此外，我们总结了一些关于如何在神经回路中发生重映射的理论。最后，基于神经生理学和心理物理学观察，我们讨论了重新映射信息可能促进下游大脑区域计算的方式。
