Visual coding is a highly dynamic process and continuously adapting to the current viewing context. The perceptual changes that result from adaptation to recently viewed stimuli remain a powerful and popular tool for analyzing sensory mechanisms and plasticity. Over the last decade, the footprints of this adaptation have been tracked to both higher and lower levels of the visual pathway and over a wider range of timescales, revealing that visual processing is much more adaptable than previously thought. This work has also revealed that the pattern of aftereffects is similar across many stimulus dimensions, pointing to common coding principles in which adaptation plays a central role. However, why visual coding adapts has yet to be fully answered.
视觉编码是一个高度动态的过程，并且不断适应当前的观看环境。因适应最近观看的刺激而产生的感知变化，仍然是分析感觉机制和可塑性的一种强大且常用的工具。在过去十年中，这种适应的痕迹已被追踪到视觉通路的更高和更低层次，以及更广泛的时间尺度上，这表明视觉处理比之前认为的更具适应性。这项工作还表明，后效应的模式在许多刺激维度上是相似的，这指向了以适应为核心作用的共同编码原则。然而，视觉编码为何会适应尚未得到充分解答。
