Abstract

Prior physiological studies indicate that gaze direction modulates the gain of neural responses to visual stimuli. Here, we test gaze modulation in the perceptual domain using color and depth aftereffects. After confirming retinotopy of the effects, we employed a balanced alternating adaptation paradigm (adaptation alternates between opponent stimuli) to demonstrate that opposite color and depth aftereffects can co-develop at the same retinal location for different gaze directions. The results provide strong evidence for (a) gaze modulation of aftereffects, (b) generality of gaze modulation across two visual attributes, and (c) perceptual correlates of the modulation of neural activity by gaze direction.

摘要

先前的生理学研究表明，注视方向会调节神经对视觉刺激的反应增益。在此，我们使用颜色和深度后效在感知领域测试注视调节。在确认了这些效应的视网膜拓扑结构后，我们采用了一种平衡交替适应范式（在对立刺激之间交替适应）来证明，对于不同的注视方向，相反的颜色和深度后效可以在同一视网膜位置共同产生。这些结果为以下几点提供了有力证据：（a）后效的注视调节；（b）注视调节在两种视觉属性上的普遍性；（c）注视方向对神经活动调节的感知相关物。
