Primates' retinal ganglion cells in different visual pathways have been shown to adapt independently (Current Biology 22 (2012) 220-224). However, the manner in which adaptation occurs under simultaneous stimulation of two visual pathways has not yet been explored. In this study, the dynamics of color afterimages were measured while stimulating one or two visual pathway using a time-varying afterimage paradigm. The dynamics of adaptation was approximately equivalent among the three primary visual pathways, but adaptation was slower for simultaneous stimulation of two visual pathways compared to the stimulation of one visual pathway. In addition, we found that the speed of adaptation also depends upon which two pathways are combined. We developed a two-stage adaptation model, both with the same dynamics, to account for the results with simultaneous stimulation of two pathways.

两种视觉通路同时刺激的视觉适应动力学。

灵长类动物在不同视觉通路中的视网膜神经节细胞已被证明可以独立适应（Current Biology 22 (2012) 220-224）。然而，在两条视觉通路的同时刺激下发生适应的方式尚未被探索。在这项研究中，在使用时变残像范式刺激一个或两个视觉通路的同时，测量了彩色残像的动态。三种主要视觉通路的适应动态大致相同，但与刺激一条视觉通路相比，同时刺激两条视觉通路的适应速度较慢。此外，我们发现适应的速度还取决于哪两条路径结合在一起。我们开发了一个两阶段适应模型，两者都具有相同的动态，
